Using the occ Command

ownCloud’s occ command (ownCloud console) is ownCloud’s command-line interface. You can perform many common server operations with occ, such as installing and upgrading ownCloud, managing users and groups, encryption, passwords, LDAP setting, and more.

occ is in the owncloud/ directory; for example /var/www/owncloud on Ubuntu Linux. occ is a PHP script. You must run it as your HTTP user to ensure that the correct permissions are maintained on your ownCloud files and directories.

Run occ As Your HTTP User

The HTTP user is different on the various Linux distributions. See Set Strong Directory Permissions to learn how to find your HTTP user.

  • The HTTP user and group in Debian/Ubuntu is www-data.
  • The HTTP user and group in Fedora/CentOS is apache.
  • The HTTP user and group in Arch Linux is http.
  • The HTTP user in openSUSE is wwwrun, and the HTTP group is www.

If your HTTP server is configured to use a different PHP version than the default (/usr/bin/php), occ should be run with the same version. For example, in CentOS 6.5 with SCL-PHP54 installed, the command looks like this:

sudo -u apache /opt/rh/php54/root/usr/bin/php /var/www/html/owncloud/occ

Running occ with no options lists all commands and options, like this example on Ubuntu:

sudo -u www-data php occ
ownCloud version 9.0.0

Usage:
 command [options] [arguments]

Options:
 -h, --help            Display this help message
 -q, --quiet           Do not output any message
 -V, --version         Display this application version
     --ansi            Force ANSI output
     --no-ansi         Disable ANSI output
 -n, --no-interaction  Do not ask any interactive question
     --no-warnings     Skip global warnings, show command output only
 -v|vv|vvv, --verbose  Increase the verbosity of messages: 1 for normal output,
                       2 for more verbose output and 3 for debug

Available commands:
 check                 check dependencies of the server
                       environment
 help                  Displays help for a command
 list                  Lists commands
 status                show some status information
 upgrade               run upgrade routines after installation of
                       a new release. The release has to be
                       installed before.

This is the same as sudo -u www-data php occ list. Run it with the -h option for syntax help:

sudo -u www-data php occ -h

Display your ownCloud version:

sudo -u www-data php occ -V
  ownCloud version 9.0.0

Query your ownCloud server status:

sudo -u www-data php occ status
  - installed: true
  - version: 9.0.0.19
  - versionstring: 9.0.0
  - edition:

occ has options, commands, and arguments. Commands are required. Options are optional. Arguments can be required or optional. The, generic, syntax is:

occ [options] command [arguments]

Get detailed information on individual commands with the help command, like this example for the maintenance:mode command

sudo -u www-data php occ help maintenance:mode
Usage:
 maintenance:mode [options]

Options:
     --on              enable maintenance mode
     --off             disable maintenance mode
 -h, --help            Display this help message
 -q, --quiet           Do not output any message
 -V, --version         Display this application version
     --ansi            Force ANSI output
     --no-ansi         Disable ANSI output
 -n, --no-interaction  Do not ask any interactive question
     --no-warnings     Skip global warnings, show command output only
 -v|vv|vvv, --verbose  Increase the verbosity of messages: 1 for normal output,
                       2 for more verbose output and 3 for debug

The status command from above has an option to define the output format. The default is plain text, but it can also be json:

sudo -u www-data php occ status --output=json
{"installed":true,"version":"9.0.0.19","versionstring":"9.0.0","edition":""}

or json_pretty:

sudo -u www-data php occ status --output=json_pretty
{
   "installed": true,
   "version": "9.0.0.19",
   "versionstring": "9.0.0",
   "edition": ""
}

This output option is available on all list and list-like commands, which include status, check, app:list, config:list, encryption:status and encryption:list-modules.

Apps Commands

The app commands list, enable, and disable apps

app
 app:check-code   check code to be compliant
 app:disable      disable an app
 app:enable       enable an app
 app:getpath      Get an absolute path to the app directory
 app:list         List all available apps

List all of your installed apps or optionally provide a search pattern to restrict the list of apps to those whose name matches the given regular expression. The output shows whether they are enabled or disabled

sudo -u www-data php occ app:list [<search-pattern>]

Enable an app, for example the Market app

sudo -u www-data php occ app:enable market
market enabled

Disable an app

sudo -u www-data php occ app:disable market
market disabled

app:check-code has multiple checks: it checks if an app uses ownCloud’s public API (OCP) or private API (OC_), and it also checks for deprecated methods and the validity of the info.xml file. By default all checks are enabled. The Activity app is an example of a correctly-formatted app

sudo -u www-data php occ app:check-code notifications
App is compliant - awesome job!

If your app has issues, you’ll see output like this

sudo -u www-data php occ app:check-code foo_app
Analysing /var/www/owncloud/apps/files/foo_app.php
4 errors
   line   45: OCP\Response - Static method of deprecated class must not be
   called
   line   46: OCP\Response - Static method of deprecated class must not be
   called
   line   47: OCP\Response - Static method of deprecated class must not be
   called
   line   49: OC_Util - Static method of private class must not be called

You can get the full file path to an app

sudo -u www-data php occ app:getpath notifications
/var/www/owncloud/apps/notifications

Background Jobs Selector

Use the background command to select which scheduler you want to use for controlling background jobs, Ajax, Webcron, or Cron. This is the same as using the Cron section on your ownCloud Admin page.

background
 background:ajax       Use ajax to run background jobs
 background:cron       Use cron to run background jobs
 background:webcron    Use webcron to run background jobs

This example selects Ajax:

sudo -u www-data php occ background:ajax
  Set mode for background jobs to 'ajax'

The other two commands are:

  • background:cron
  • background:webcron

See Background Jobs to learn more.

Config Commands

The config commands are used to configure the ownCloud server.

config
 config:app:delete      Delete an app config value
 config:app:get         Get an app config value
 config:app:set         Set an app config value
 config:import          Import a list of configuration settings
 config:list            List all configuration settings
 config:system:delete   Delete a system config value
 config:system:get      Get a system config value
 config:system:set      Set a system config value

You can list all configuration values with one command:

sudo -u www-data php occ config:list

By default, passwords and other sensitive data are omitted from the report, so the output can be posted publicly (e.g., as part of a bug report). In order to generate a full backport of all configuration values the --private flag needs to be set:

sudo -u www-data php occ config:list --private

The exported content can also be imported again to allow the fast setup of similar instances. The import command will only add or update values. Values that exist in the current configuration, but not in the one that is being imported are left untouched.

sudo -u www-data php occ config:import filename.json

It is also possible to import remote files, by piping the input:

sudo -u www-data php occ config:import < local-backup.json

Note

While it is possible to update/set/delete the versions and installation statuses of apps and ownCloud itself, it is not recommended to do this directly. Use the occ app:enable, occ app:disable and occ update commands instead.

Getting a Single Configuration Value

These commands get the value of a single app or system configuration:

sudo -u www-data php occ config:system:get version
9.0.0.19

sudo -u www-data php occ config:app:get activity installed_version
2.2.1

Setting a Single Configuration Value

These commands set the value of a single app or system configuration:

sudo -u www-data php occ config:system:set logtimezone
--value="Europe/Berlin"
System config value logtimezone set to Europe/Berlin

sudo -u www-data php occ config:app:set files_sharing
incoming_server2server_share_enabled --value="yes" --type=boolean
Config value incoming_server2server_share_enabled for app files_sharing set to yes

The config:system:set command creates the value, if it does not already exist. To update an existing value, set --update-only:

sudo -u www-data php occ config:system:set doesnotexist --value="true"
--type=boolean --update-only
Value not updated, as it has not been set before.

Note that in order to write a Boolean, float, or integer value to the configuration file, you need to specify the type on your command. This applies only to the config:system:set command. The following values are known:

  • boolean
  • integer
  • float
  • string (default)

When you want to e.g., disable the maintenance mode run the following command:

sudo -u www-data php occ config:system:set maintenance --value=false
--type=boolean
ownCloud is in maintenance mode - no app have been loaded
System config value maintenance set to boolean false

Setting an Array of Configuration Values

Some configurations (e.g., the trusted domain setting) are an array of data. In order to set (and also get) the value of one key, you can specify multiple config names separated by spaces:

sudo -u www-data php occ config:system:get trusted_domains
localhost
owncloud.local
sample.tld

To replace sample.tld with example.com trusted_domains => 2 needs to be set:

sudo -u www-data php occ config:system:set trusted_domains 2
--value=example.com
System config value trusted_domains => 2 set to string example.com

sudo -u www-data php occ config:system:get trusted_domains
localhost
owncloud.local
example.com

Deleting a Single Configuration Value

These commands delete the configuration of an app or system configuration:

sudo -u www-data php occ config:system:delete maintenance:mode
System config value maintenance:mode deleted

sudo -u www-data php occ config:app:delete appname provisioning_api
Config value provisioning_api of app appname deleted

The delete command will by default not complain if the configuration was not set before. If you want to be notified in that case, set the --error-if-not-exists flag.

sudo -u www-data php occ config:system:delete doesnotexist
--error-if-not-exists
Config provisioning_api of app appname could not be deleted because it did not
exist

Dav Commands

A set of commands to create address books, calendars, and to migrate address books:

dav
 dav:create-addressbook        Create a dav address book
 dav:create-calendar           Create a dav calendar
 dav:sync-birthday-calendar    Synchronizes the birthday calendar
 dav:sync-system-addressbook   Synchronizes users to the system
                               address book

Note

These commands are not available in single-user (maintenance) mode.

The syntax for dav:create-addressbook and dav:create-calendar is dav:create-addressbook [user] [name]. This example creates the addressbook mollybook for the user molly:

sudo -u www-data php occ dav:create-addressbook molly mollybook

This example creates a new calendar for molly:

sudo -u www-data php occ dav:create-calendar molly mollycal

Molly will immediately see these on her Calendar and Contacts pages. Your existing calendars and contacts should migrate automatically when you upgrade. If something goes wrong you can try a manual migration. First delete any partially-migrated calendars or address books. Then run this command to migrate user’s contacts:

sudo -u www-data php occ dav:migrate-addressbooks [user]

Run this command to migrate calendars:

sudo -u www-data php occ dav:migrate-calendars [user]

dav:sync-birthday-calendar adds all birthdays to your calendar from address books shared with you. This example syncs to your calendar from user bernie:

sudo -u www-data php occ dav:sync-birthday-calendar bernie

dav:sync-system-addressbook synchronizes all users to the system addressbook.

sudo -u www-data php occ dav:sync-system-addressbook

Database Conversion

The SQLite database is good for testing, and for ownCloud servers with small single-user workloads that do not use sync clients, but production servers with multiple users should use MariaDB, MySQL, or PostgreSQL. You can use occ to convert from SQLite to one of these other databases.

db
 db:convert-type           Convert the ownCloud database to the newly
                           configured one
 db:generate-change-script generates the change script from the current
                           connected db to db_structure.xml

You need:

  • Your desired database and its PHP connector installed.
  • The login and password of a database admin user.
  • The database port number, if it is a non-standard port.

This is example converts SQLite to MySQL/MariaDB:

sudo -u www-data php occ db:convert-type mysql oc_dbuser 127.0.0.1
oc_database

For a more detailed explanation see Converting Database Type.

Encryption

occ includes a complete set of commands for managing encryption.

encryption
 encryption:change-key-storage-root   Change key storage root
 encryption:decrypt-all               Disable server-side encryption and
                                      decrypt all files
 encryption:disable                   Disable encryption
 encryption:enable                    Enable encryption
 encryption:enable-master-key         Enable the master key. Only available
                                      for fresh installations with no existing
                                      encrypted data! There is also no way to
                                      disable it again.
 encryption:encrypt-all               Encrypt all files for all users
 encryption:list-modules              List all available encryption modules
 encryption:migrate                   initial migration to encryption 2.0
 encryption:set-default-module        Set the encryption default module
 encryption:show-key-storage-root     Show current key storage root
 encryption:status                    Lists the current status of encryption

encryption:status shows whether you have active encryption, and your default encryption module. To enable encryption you must first enable the Encryption app, and then run encryption:enable:

sudo -u www-data php occ app:enable encryption
sudo -u www-data php occ encryption:enable
sudo -u www-data php occ encryption:status
 - enabled: true
 - defaultModule: OC_DEFAULT_MODULE

encryption:change-key-storage-root is for moving your encryption keys to a different folder. It takes one argument, newRoot, which defines your new root folder. The folder must exist, and the path is relative to your root ownCloud directory.

sudo -u www-data php occ encryption:change-key-storage-root ../../etc/oc-keys

You can see the current location of your keys folder:

sudo -u www-data php occ encryption:show-key-storage-root
Current key storage root:  default storage location (data/)

encryption:list-modules displays your available encryption modules. You will see a list of modules only if you have enabled the Encryption app. Use encryption:set-default-module [module name] to set your desired module.

encryption:encrypt-all encrypts all data files for all users. You must first put your ownCloud server into single-user mode to prevent any user activity until encryption is completed.

encryption:decrypt-all decrypts all user data files, or optionally a single user:

sudo -u www-data php occ encryption:decrypt freda

Users must have enabled recovery keys on their Personal pages. You must first put your ownCloud server into single-user mode to prevent any user activity until decryption is completed.

Use encryption:disable to disable your encryption module. You must first put your ownCloud server into single-user mode to prevent any user activity.

encryption:enable-master-key creates a new master key, which is used for all user data instead of individual user keys. This is especially useful to enable single-sign on. Use this only on fresh installations with no existing data, or on systems where encryption has not already been enabled. It is not possible to disable it.

encryption:migrate migrates encryption keys after a major ownCloud version upgrade. You may optionally specify individual users in a space-delimited list. See Encryption Configuration to learn more.

Federation Sync

Synchronize the address books of all federated ownCloud servers:

federation:sync-addressbooks  Synchronizes address books of all
                              federated clouds

Servers connected with federation shares can share user address books, and auto-complete usernames in share dialogs. Use this command to synchronize federated servers:

sudo -u www-data php occ federation:sync-addressbooks

Note

This command is only available when the “Federation” app (federation) is enabled.

File Operations

occ has three commands for managing files in ownCloud:

files
 files:cleanup              Deletes orphaned file cache entries.
 files:scan                 Rescans the filesystem.
 files:transfer-ownership   All files and folders are moved to another
                            user - shares are moved as well.

Note

These commands are not available in single-user (maintenance) mode.

The files:scan command scans for new files and updates the file cache. You may rescan all files, per-user, a space-delimited list of users, and limit the search path. If not using --quiet, statistics will be shown at the end of the scan:

sudo -u www-data php occ files:scan --help
  Usage:
  files:scan [-p|--path="..."] [-q|--quiet] [-v|vv|vvv --verbose] [--all]
  [user_id1] ... [user_idN]

Arguments:
  user_id               will rescan all files of the given user(s)

Options:
  --path                limit rescan to the user/path given
  --all                 will rescan all files of all known users
  --quiet               suppress any output
  --verbose             files and directories being processed are shown
                        additionally during scanning
  --unscanned           scan only previously unscanned files

Verbosity levels of -vv or -vvv are automatically reset to -v. With respect to the --unscanned option, in general there is a background job (through Cron) that will do that scan periodically. The --unscanned option makes it possible to trigger this from the CLI.

When using the --path option, the path must consist of following components:

"user_id/files/path"
  or
"user_id/files/mount_name"
  or
"user_id/files/mount_name/path"

For example:

--path="/alice/files/Music"

In the example above, the user_id alice is determined implicitly from the path component given. The --path, --all and [user_id] parameters and are exclusive - only one must be specified.

files:cleanup tidies up the server’s file cache by deleting all file entries that have no matching entries in the storage table. You may transfer all files and shares from one user to another. This is useful before removing a user.

For example, to move all files from <source-user> to <destination-user>, use the following command:

sudo -u www-data php occ files:transfer-ownership <source-user> <destination-user>

You can also move a limited set of files from <source-user> to <destination-user> by making use of the --path switch, as in the example below. In it, folder/to/move, and any file and folder inside it will be moved to <destination-user>.

sudo -u www-data php occ files:transfer-ownership --path="folder/to/move" <source-user> <destination-user>

When using this command keep two things in mind:

  1. The directory provided to the --path switch must exist inside data/<source-user>/files.
  2. The directory (and its contents) won’t be moved as is between the users. It’ll be moved inside the destination user’s files directory, and placed in a directory which follows the format: transferred from <source-user> on <timestamp>. Using the example above, it will be stored under: data/<destination-user>/files/transferred from <source-user> on 20170426_124510/

Files External

These commands replace the data/mount.json configuration file used in ownCloud releases before 9.0.

Commands for managing external storage:

files_external
 files_external:applicable  Manage applicable users and groups for a mount
 files_external:backends    Show available authentication and storage backends
 files_external:config      Manage backend configuration for a mount
 files_external:create      Create a new mount configuration
 files_external:delete      Delete an external mount
 files_external:export      Export mount configurations
 files_external:import      Import mount configurations
 files_external:list        List configured mounts
 files_external:option      Manage mount options for a mount
 files_external:verify      Verify mount configuration

These commands replicate the functionality in the ownCloud Web GUI, plus two new features: files_external:export and files_external:import.

Use files_external:export to export all admin mounts to stdout, and files_external:export [user_id] to export the mounts of the specified ownCloud user.

Note

These commands are only available when the “External storage support” app (files_external) is enabled. It is not available in single-user (maintenance) mode.

Group Commands

The group commands provide a range of functionality for managing ownCloud groups. This includes creating and removing groups and managing group membership. Group names are case-sensitive, so “Finance” and “finance” are two different groups.

The full list of commands is:

group
 group:add                           adds a group
 group:add-member                    add members to a group
 group:delete                        deletes the specified group
 group:remove-member                 remove member(s) from a group

Creating Groups

You can create a new group with the group:add command. The syntax is:

group:add groupname

This example adds a new group, called “Finance”:

sudo -u www-data php occ group:add Finance
  Created group "Finance"

Adding Members to Groups

You can add members to an existing group with the group:add-member command. Members must be existing users. The syntax is:

group:add-member [-m|--member [MEMBER]] <group>

This example adds members “aaron” and “julie” to group “Finance”:

sudo -u www-data php occ group:add-member --member aaron --member julie Finance
  User "aaron" added to group "Finance"
  User "julie" added to group "Finance"

You may attempt to add members that are already in the group, without error. This allows you to add members in a scripted way without needing to know if the user is already a member of the group. For example:

sudo -u www-data php occ group:add-member --member aaron --member julie --member fred Finance
  User "aaron" is already a member of group "Finance"
  User "julie" is already a member of group "Finance"
  User fred" added to group "Finance"

Removing Members from Groups

You can remove members from a group with the group:remove-member command. The syntax is:

group:remove-member [-m|--member [MEMBER]] <group>

This example removes members “aaron” and “julie” from group “Finance”:

sudo -u www-data php occ group:remove-member --member aaron --member julie Finance
  Member "aaron" removed from group "Finance"
  Member "julie" removed from group "Finance"

You may attempt to remove members that have already been removed from the group, without error. This allows you to remove members in a scripted way without needing to know if the user is still a member of the group. For example:

sudo -u www-data php occ group:remove-member --member aaron --member fred Finance
  Member "aaron" could not be found in group "Finance"
  Member "fred" removed from group "Finance"

Deleting a Group

To delete a group, you use the group:delete command, as in the example below:

sudo -u www-data php occ group:delete Finance

Integrity Check

Apps which have an official tag MUST be code signed. Unsigned official apps won’t be installable anymore. Code signing is optional for all third-party applications.

integrity
 integrity:check-app                 Check app integrity using a signature.
 integrity:check-core                Check core integrity using a signature.
 integrity:sign-app                  Signs an app using a private key.
 integrity:sign-core                 Sign core using a private key

After creating your signing key, sign your app like this example:

sudo -u www-data php occ integrity:sign-app --privateKey=/Users/lukasreschke/contacts.key --certificate=/Users/lukasreschke/CA/contacts.crt --path=/Users/lukasreschke/Programming/contacts

Verify your app:

sudo -u www-data php occ integrity:check-app --path=/pathto/app appname

When it returns nothing, your app is signed correctly. When it returns a message then there is an error. See Code Signing in the Developer manual for more detailed information.

integrity:sign-core is for ownCloud core developers only.

See Code Signing to learn more.

l10n, Create Javascript Translation Files for Apps

This command is for app developers to update their translation mechanism from ownCloud 7 to ownCloud 8 and later.

LDAP Commands

Note

These commands are only available when the “LDAP user and group backend” app (user_ldap) is enabled.

These LDAP commands appear only when you have enabled the LDAP app. Then you can run the following LDAP commands with occ:

ldap
 ldap:check-user               checks whether a user exists on LDAP.
 ldap:create-empty-config      creates an empty LDAP configuration
 ldap:delete-config            deletes an existing LDAP configuration
 ldap:search                   executes a user or group search
 ldap:set-config               modifies an LDAP configuration
 ldap:show-config              shows the LDAP configuration
 ldap:test-config              tests an LDAP configuration
 ldap:update-group             update the specified group membership
                               information stored locally

Search for an LDAP user, using this syntax:

sudo -u www-data php occ ldap:search [--group] [--offset="..."]
[--limit="..."] search

Searches will match at the beginning of the attribute value only. This example searches for givenNames that start with “rob”:

sudo -u www-data php occ ldap:search "rob"

This will find robbie, roberta, and robin. Broaden the search to find, for example, jeroboam with the asterisk wildcard:

sudo -u www-data php occ ldap:search "*rob"

User search attributes are set with ldap:set-config (below). For example, if your search attributes are givenName and sn you can find users by first name + last name very quickly. For example, you’ll find Terri Hanson by searching for te ha. Trailing whitespace is ignored.

Check if an LDAP user exists. This works only if the ownCloud server is connected to an LDAP server.

sudo -u www-data php occ ldap:check-user robert

ldap:check-user will not run a check when it finds a disabled LDAP connection. This prevents users that exist on disabled LDAP connections from being marked as deleted. If you know for certain that the user you are searching for is not in one of the disabled connections, and exists on an active connection, use the --force option to force it to check all active LDAP connections.

sudo -u www-data php occ ldap:check-user --force robert

ldap:create-empty-config creates an empty LDAP configuration. The first one you create has no configID, like this example:

sudo -u www-data php occ ldap:create-empty-config
  Created new configuration with configID ''

This is a holdover from the early days, when there was no option to create additional configurations. The second, and all subsequent, configurations that you create are automatically assigned IDs.

sudo -u www-data php occ ldap:create-empty-config
   Created new configuration with configID 's01'

Then you can list and view your configurations:

sudo -u www-data php occ ldap:show-config

And view the configuration for a single configID:

sudo -u www-data php occ ldap:show-config s01

ldap:delete-config [configID] deletes an existing LDAP configuration.

sudo -u www-data php occ ldap:delete  s01
Deleted configuration with configID 's01'

The ldap:set-config command is for manipulating configurations, like this example that sets search attributes:

sudo -u www-data php occ ldap:set-config s01 ldapAttributesForUserSearch
"cn;givenname;sn;displayname;mail"

The command takes the following format:

ldap:set-config <configID> <configKey> <configValue>

All of the available keys, along with default values for configValue, are listed in the table below.

ldap:test-config tests whether your configuration is correct and can bind to the server.

sudo -u www-data php occ ldap:test-config s01
The configuration is valid and the connection could be established!

ldap:update-group updates the specified group membership information stored locally.

The command takes the following format:

ldap:update-group <groupID> <groupID <groupID> ...>

The command allows for running a manual group sync on one or more groups, instead of having to wait for group syncing to occur. If users have been added or removed from these groups in LDAP, ownCloud will update its details. If a group was deleted in LDAP, ownCloud will also delete the local mapping info about this group.

Note

New groups in LDAP won’t be synced with this command. The LDAP TTL configuration (by default 10 minutes) still applies. This means that recently deleted groups from LDAP might be considered as “active” and might not be deleted in ownCloud immediately.

Configuring the LDAP Refresh Attribute Interval

You can configure the LDAP refresh attribute interval, but not with the ldap commands. Instead, you need to use the config:app:set command, as in the following example, which takes a number of seconds to the --value switch.

occ config:app:set user_ldap updateAttributesInterval --value=7200

In the example above, the interval is being set to 7200 seconds. Assuming the above example was used, the command would output the following:

Config value updateAttributesInterval for app user_ldap set to 7200

If you want to reset (or unset) the setting, then you can use the following command:

occ config:app:delete user_ldap updateAttributesInterval

Logging Commands

These commands view and configure your ownCloud logging preferences.

log
 log:manage     manage logging configuration
 log:owncloud   manipulate ownCloud logging backend

Run log:owncloud to see your current logging status:

sudo -u www-data php occ log:owncloud
Log backend ownCloud: enabled
Log file: /opt/owncloud/data/owncloud.log
Rotate at: disabled

Use the --enable option to turn on logging. Use --file to set a different log file path. Set your rotation by log file size in bytes with --rotate-size; 0 disables rotation. log:manage sets your logging backend, log level, and timezone. The defaults are owncloud, Warning, and UTC. Available options are:

  • –backend [owncloud, syslog, errorlog]
  • –level [debug, info, warning, error, fatal]

Maintenance Commands

Use these commands when you upgrade ownCloud, manage encryption, perform backups and other tasks that require locking users out until you are finished:

maintenance
 maintenance:data-fingerprint        update the systems data-fingerprint after
                                     a backup is restored
 maintenance:mimetype:update-db      Update database mimetypes and update
                                     filecache
 maintenance:mimetype:update-js      Update mimetypelist.js
 maintenance:mode                    set maintenance mode
 maintenance:repair                  repair this installation
 maintenance:singleuser              set single user mode
 maintenance:update:htaccess         Updates the .htaccess file

maintenance:mode locks the sessions of all logged-in users, including administrators, and displays a status screen warning that the server is in maintenance mode. Users who are not already logged in cannot log in until maintenance mode is turned off. When you take the server out of maintenance mode logged-in users must refresh their Web browsers to continue working.

sudo -u www-data php occ maintenance:mode --on
sudo -u www-data php occ maintenance:mode --off

Putting your ownCloud server into single-user mode allows admins to log in and work, but not ordinary users. This is useful for performing maintenance and troubleshooting on a running server.

sudo -u www-data php occ maintenance:singleuser --on
Single user mode enabled

Turn it off when you’re finished:

sudo -u www-data php occ maintenance:singleuser --off
Single user mode disabled

Run maintenance:data-fingerprint to tell desktop and mobile clients that a server backup has been restored. Users will be prompted to resolve any conflicts between newer and older file versions.

Run maintenance:data-fingerprint to tell desktop and mobile clients that a server backup has been restored. This command changes the ETag for all files in the communication with sync clients, informing them that one or more files were modified. After the command completes, users will be prompted to resolve any conflicts between newer and older file versions.

The maintenance:repair command runs automatically during upgrades to clean up the database, so while you can run it manually there usually isn’t a need to.

sudo -u www-data php occ maintenance:repair

maintenance:mimetype:update-db updates the ownCloud database and file cache with changed mimetypes found in config/mimetypemapping.json. Run this command after modifying config/mimetypemapping.json. If you change a mimetype, run maintenance:mimetype:update-db --repair-filecache to apply the change to existing files.

Market

The market commands install, list, and upgrade applications from the ownCloud Marketplace.

market
  market:install    Install apps from the marketplace. If already installed and
                    an update is available the update will be installed.
  market:list       Lists apps as available on the marketplace.
  market:upgrade    Installs new app versions if available on the marketplace

Note

The user running the update command, which will likely be your webserver user, needs write permission for the /apps folder. If they don’t have write permission, the command may report that the update was successful, but it may silently fail.

Note

These commands are not available in single-user (maintenance) mode.

Market

The market commands install, list, and upgrade applications from the ownCloud Marketplace.

market
  market:install    Install apps from the marketplace. If already installed and
                    an update is available the update will be installed.
  market:list       Lists apps as available on the marketplace.
  market:upgrade    Installs new app versions if available on the marketplace

Note

The user running the update command, which will likely be your webserver user, needs write permission for the /apps folder. If they don’t have write permission, the command may report that the update was successful, but it may silently fail.

Reports

If you’re working with ownCloud support and need to send them a configuration summary, you can generate it using the configreport:generate command. This command generates the same JSON-based report as the Admin Config Report, which you can access under admin -> Settings -> Admin -> Help & Tips -> Download ownCloud config report.

From the command-line in the root directory of your ownCloud installation, run it as your webserver user as follows, (assuming your webserver user is www-data):

sudo -u www-data occ configreport:generate

This will generate the report and send it to STDOUT. You can optionally pipe the output to a file and then attach it to an email to ownCloud support, by running the following command:

sudo -u www-data occ configreport:generate > generated-config-report.txt

Alternatively, you could generate the report and email it all in one command, by running:

sudo -u www-data occ configreport:generate | mail -s "configuration report" \
    -r <the email address to send from> \
    support@owncloud.com

Note

These commands are not available in single-user (maintenance) mode.

Security

Use these commands to manage server-wide SSL certificates. These are useful when you create federation shares with other ownCloud servers that use self-signed certificates.

security
 security:certificates         list trusted certificates
 security:certificates:import  import trusted certificate
 security:certificates:remove  remove trusted certificate

This example lists your installed certificates:

sudo -u www-data php occ security:certificates

Import a new certificate:

sudo -u www-data php occ security:import /path/to/certificate

Remove a certificate:

sudo -u www-data php occ security:remove [certificate name]

Sharing

This is an occ command to cleanup orphaned remote storages. To explain why this is necessary, a little background is required. While shares are able to be deleted as a normal matter of course, remote storages with “shared::” are not included in this process.

This might not, normally, be a problem. However, if a user has re-shared a remote share which has been deleted it will. This is because when the original share is deleted, the remote re-share reference is not. Internally, the fileid will remain in the file cache and storage for that file will not be deleted.

As a result, any user(s) who the share was re-shared with will now get an error when trying to access that file or folder. That’s why the command is available.

So, to cleanup all orphaned remote storages, run it as follows:

sudo -u www-data php sharing:cleanup-remote-storages

You can also set it up to run as a background job

Note

These commands are not available in single-user (maintenance) mode.

Shibboleth Modes (Enterprise Edition only)

shibboleth:mode sets your Shibboleth mode to notactive, autoprovision, or ssoonly:

shibboleth:mode [mode]

Note

These commands are only available when the “Shibboleth user backend” app (user_shibboleth) is enabled.

Trashbin

Note

These commands are only available when the “Deleted files” app (files_trashbin) is enabled. These commands are not available in single-user (maintenance) mode.

trashbin
 trashbin:cleanup   Remove deleted files
 trashbin:expire    Expires the users trash bin

The trashbin:cleanup command removes the deleted files of the specified users in a space-delimited list, or all users if none are specified. This example removes all the deleted files of all users:

sudo -u www-data php occ trashbin:cleanup
Remove all deleted files
Remove deleted files for users on backend Database
 freda
 molly
 stash
 rosa
 edward

This example removes the deleted files of users “”molly”” and “”freda””:

sudo -u www-data php occ trashbin:cleanup molly freda
Remove deleted files of   molly
Remove deleted files of   freda

trashbin:expire deletes only expired files according to the trashbin_retention_obligation setting in config.php (see the Deleted Files section in Config.php Parameters). The default is to delete expired files for all users, or you may list users in a space-delimited list.

User Commands

The user commands provide a range of functionality for managing ownCloud users. This includes: creating and removing users, resetting user passwords, displaying a report which shows how many users you have, and when a user was last logged in.

The full list, of commands is:

user
 user:add                            adds a user
 user:delete                         deletes the specified user
 user:disable                        disables the specified user
 user:enable                         enables the specified user
 user:inactive                       reports users who are known to owncloud,
                                     but have not logged in for a certain number of days
 user:lastseen                       shows when the user was logged in last time
 user:report                         shows how many users have access
 user:resetpassword                  Resets the password of the named user
 user:setting                        Read and modify user settings
 user:sync                           Sync local users with an external backend service

Creating Users

You can create a new user with the user:add command. This command lets you set the following attributes:

  • uid: The uid is the user’s username and their login name
  • display name: This corresponds to the Full Name on the Users page in your ownCloud Web UI
  • email address
  • group
  • login name
  • password

The command’s syntax is:

user:add [--password-from-env] [--display-name [DISPLAY-NAME]] [--email [EMAIL]] [-g|--group [GROUP]] [--] <uid>

This example adds new user Layla Smith, and adds her to the users and db-admins groups. Any groups that do not exist are created.

sudo -u www-data php occ user:add --display-name="Layla Smith" \
  --group="users" --group="db-admins" --email=layla.smith@example.com layla
  Enter password:
  Confirm password:
  The user "layla" was created successfully
  Display name set to "Layla Smith"
  Email address set to "layla.smith@example.com"
  User "layla" added to group "users"
  User "layla" added to group "db-admins"

After the command completes, go to your Users page, and you will see your new user.

Setting a User’s Password

password-from-env allows you to set the user’s password from an environment variable. This prevents the password from being exposed to all users via the process list, and will only be visible in the history of the user (root) running the command. This also permits creating scripts for adding multiple new users.

To use password-from-env you must run as “real” root, rather than sudo, because sudo strips environment variables. This example adds new user Fred Jones:

export OC_PASS=newpassword
su -s /bin/sh www-data -c 'php occ user:add --password-from-env
  --display-name="Fred Jones" --group="users" fred'
The user "fred" was created successfully
Display name set to "Fred Jones"
User "fred" added to group "users"

You can reset any user’s password, including administrators (see Resetting a Lost Admin Password):

sudo -u www-data php occ user:resetpassword layla
  Enter a new password:
  Confirm the new password:
  Successfully reset password for layla

You may also use password-from-env to reset passwords:

export OC_PASS=newpassword
su -s /bin/sh www-data -c 'php occ user:resetpassword --password-from-env
  layla'
  Successfully reset password for layla

Deleting A User

To delete a user, you use the user:delete command, as in the example below:

sudo -u www-data php occ user:delete fred

Finding The User’s Last Login

To view a user’s most recent login, use the user:lastseen command, as in the example below:

sudo -u www-data php occ user:lastseen layla
  layla's last login: 09.01.2015 18:46

User Application Settings

To manage application settings for a user, use the user:setting command. This command provides the ability to:

  • Retrieve all settings for an application
  • Retrieve a single setting
  • Set a setting value
  • Delete a setting

If you run the command and pass the help switch (--help), you will see the following output, in your terminal:

$ ./occ user:setting --help
Usage:
  user:setting [options] [--] <uid> [<app>] [<key>]

Arguments:
  uid                                User ID used to login
  app                                Restrict the settings to a given app [default: ""]
  key                                Setting key to set, get or delete [default: ""]

If you’re new to the user:setting command, the descriptions for the app and key arguments may not be completely transparent. So, here’s a lengthier description of both.

Argument Description
app When an value is supplied, user:setting limits the settings displayed, to those for that, specific, application — assuming that the application is installed, and that there are settings available for it. Some example applications are “core”, “files_trashbin”, and “user_ldap”. A complete list, unfortunately, cannot be supplied, as it is impossible to know the entire list of applications which a user could, potentially, install.
key This value specifies the setting key to be manipulated (set, retrieved, or deleted) by the user:setting command.

Retrieving User Settings

To retrieve all settings for a user, you need to call the user:setting command and supply the user’s username, as in the example below.

sudo -u www-data php occ user:setting layla
  - core:
    - lang: en
  - login:
    - lastLogin: 1465910968
  - settings:
    - email: layla@example.tld

Here, we see that the user has settings for the application core, when they last logged in, and what their email address is.

To retrieve the user’s settings for a specific application, you have to supply the username and the application’s name, which you want to retrieve the settings for; such as in the example below:

sudo -u www-data php occ user:setting layla core
 - core:
    - lang: en

In the output, you can see that one setting is in effect, lang, which is set to en. To retrieve the value of a single application for a user, use the user:setting command, as in the example below.

sudo -u www-data php occ user:setting layla core lang

This will display the value for that setting, such as en.

Setting a Setting

To set a setting, you need to supply four things; these are:

  • the username
  • the application (or setting category)
  • the --value switch
  • the, quoted, value for that setting

Here’s an example of how you would set the email address of the user layla.

sudo -u www-data php occ user:setting layla settings email --value "new-layla@example.tld"

Deleting a Setting

Deleting a setting is quite similar to setting a setting. In this case, you supply the username, application (or setting category) and key as above. Then, in addition, you supply the --delete flag.

sudo -u www-data php occ user:setting layla settings email --delete

Generating a User Count Report

Generate a simple report that counts all users, including users on external user authentication servers such as LDAP.

sudo -u www-data php occ user:report
+------------------+----+
| User Report      |    |
+------------------+----+
| Database         | 12 |
| LDAP             | 86 |
|                  |    |
| total users      | 98 |
|                  |    |
| user directories | 2  |
+------------------+----+

Syncing User Accounts

This command syncs users stored in external backend services, such as LDAP, Shibboleth, and Samba, with ownCloud’s, internal, user database. However, it’s not essential to run it regularly, unless you have a large number of users whose account properties have changed in a backend outside of ownCloud. When run, it will pick up changes from alternative user backends, such as LDAP where properties like cn or display name have changed, and sync them with ownCloud’s user database. If accounts are found that no longer exist in the external backend, you are given the choice of either removing or disabling the accounts.

Note

It’s also one of the commands that you should run on a regular basis to ensure that your ownCloud installation is running optimally.

Note

This command replaces the old show-remnants functionality, and brings the LDAP feature more in line with the rest of ownCloud’s functionality.

Below are examples of how to use the command with an LDAP, Samba, and Shibboleth backend.

LDAP

sudo -u www-data ./occ user:sync "OCA\User_LDAP\User_Proxy"

Samba

sudo -u www-data ./occ user:sync "OCA\User\SMB" -vvv

Shibboleth

sudo -u www-data ./occ user:sync "OCA\User_Shibboleth\UserBackend"

Syncing via cron job

Here is an example for syncing with LDAP four times a day on Ubuntu:

crontab -e -u www-data

  • */6 * * * /usr/bin/php /var/www/owncloud/occ user:sync -vvv –missing-account-action=”remove” -n “OCAUser_LDAPUser_Proxy”

Versions

versions
 versions:cleanup   Delete versions
 versions:expire    Expires the users file versions

versions:cleanup can delete all versioned files, as well as the files_versions folder, for either specific users, or for all users. The example below deletes all versioned files for all users:

sudo -u www-data php occ versions:cleanup
Delete all versions
Delete versions for users on backend Database
  freda
  molly
  stash
  rosa
  edward

You can delete versions for specific users in a space-delimited list:

sudo -u www-data php occ versions:cleanup freda molly
Delete versions of   freda
Delete versions of   molly

versions:expire deletes only expired files according to the versions_retention_obligation setting in config.php (see the File versions section in Config.php Parameters). The default is to delete expired files for all users, or you may list users in a space-delimited list.

Note

These commands are only available when the “Versions” app (files_versions) is enabled. These commands are not available in single-user (maintenance) mode.

Command Line Installation

ownCloud can be installed entirely from the command line. After downloading the tarball and copying ownCloud into the appropriate directories, or after installing ownCloud packages (See Preferred Installation Method and Manual Installation on Linux) you can use occ commands in place of running the graphical Installation Wizard.

Note

These instructions assume that you have a fully working and configured webserver. If not, please refer to the documentation on configuring the Apache web server for detailed instructions.

Apply correct permissions to your ownCloud directories; see Set Strong Directory Permissions. Then choose your occ options. This lists your available options:

 -v|vv|vvv, --verbose  Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

Help:
 run upgrade routines after installation of a new release. The release has to be installed before.

When you are performing an update or upgrade on your ownCloud server (see the Maintenance section of this manual), it is better to use occ to perform the database upgrade step, rather than the Web GUI, in order to avoid timeouts. PHP scripts invoked from the Web interface are limited to 3600 seconds. In larger environments this may not be enough, leaving the system in an inconsistent state. After performing all the preliminary steps (see How to Upgrade Your ownCloud Server) use this command to upgrade your databases, like this example on CentOS Linux:

sudo -u www-data php occ upgrade
ownCloud or one of the apps require upgrade - only a limited number of
commands are available
Turned on maintenance mode
Checked database schema update
Checked database schema update for apps
Updated database
Updating <gallery> ...
Updated <gallery> to 0.6.1
Updating <activity> ...
Updated <activity> to 2.1.0
Update successful
Turned off maintenance mode

Note how it details the steps. Enabling verbosity displays timestamps:

sudo -u www-data php occ upgrade -v
ownCloud or one of the apps require upgrade - only a limited number of commands are available
2015-06-23T09:06:15+0000 Turned on maintenance mode
2015-06-23T09:06:15+0000 Checked database schema update
2015-06-23T09:06:15+0000 Checked database schema update for apps
2015-06-23T09:06:15+0000 Updated database
2015-06-23T09:06:15+0000 Updated <files_sharing> to 0.6.6
2015-06-23T09:06:15+0000 Update successful
2015-06-23T09:06:15+0000 Turned off maintenance mode

If there is an error it throws an exception, and the error is detailed in your ownCloud logfile, so you can use the log output to figure out what went wrong, or to use in a bug report.

Two-factor Authentication

If a two-factor provider app is enabled, it is enabled for all users by default (though the provider can decide whether or not the user has to pass the challenge). In the case of an user losing access to the second factor (e.g., a lost phone with two-factor SMS verification), the admin can temporarily disable the two-factor check for that user via the occ command:

sudo -u www-data php occ twofactor:disable <username>

To re-enable two-factor authentication again, use the following commmand:

sudo -u www-data php occ twofactor:enable <username>

Disable Users

Admins can disable users via the occ command too:

sudo -u www-data php occ user:disable <username>

Use the following command to enable the user again:

sudo -u www-data php occ user:enable <username>

Note

Once users are disabled, their connected browsers will be disconnected.

Finding Inactive Users

To view a list of users who’ve not logged in for a given number of days, use the user:inactive command The example below searches for users inactive for five days, or more.

sudo -u www-data php occ user:inactive 5

By default, this will generate output in the following format:

- 0:
  - uid: admin
  - displayName: admin
  - inactiveSinceDays: 5

You can see the user’s user id, display name, and the number of days they’ve been inactive. If you’re passing or piping this information to another application for further processing, you can also use the --output switch to change its format. The switch supports three options, these are:

Setting Description
plain This is the default format.
json This will render the output as a JSON-encoded, but not formatted, string.
[{"uid":"admin","displayName":"admin","inactiveSinceDays":5}]
  • json_pretty: This will render the output as a JSON-encoded string, formatted for ease of readability.
[
    {
        "uid": "admin",
        "displayName": "admin",
        "inactiveSinceDays": 5
    }
]
