==Running CLI scripts==
If you have shell access to your web server, you may find various CLI (command line interface) scripts useful during Moodle administration. Core admin CLI tools are located in the <code>admin/cli/*</code> folder. Other plugins may provide CLI functionality via scripts in their own <code>cli</code> folder.

To avoid problems with access control, you should run them as the owner of the web server process. It is especially important for CLI installation and upgrade as they create new files in moodledata directory and the web server has to have write access to them. In Linux distributions, the user that runs the web server is usually apache or www-data or httpd or something similar. As a root, you will probably want to execute Moodle CLI scripts like this:
    $ cd /path/to/your/moodle/dir
    $ sudo -u apache /usr/bin/php admin/cli/somescript.php --params
Most of the scripts accept common --help (or -h) parameter to display the full usage information, for example:
    $ sudo -u apache /usr/bin/php admin/cli/install.php --help
{{Note|These scripts are supposed to be run under the identity of the web server user. Examples on this page use the <tt>apache</tt> user for illustration. The particular value depends on your OS distribution and local set-up. Typical values may be <tt>apache</tt>, <tt>www-data</tt> or <tt>httpd</tt>.}}
== Upgrading ==
Moodle can be upgraded from the command line. As with the installation script, there is either interactive or non-interactive mode of the upgrade. The script itself does not put the site into the maintenance mode, you have to do it on your own. Also, the script does not backup any data (if you read this page, you probably have some own scripts to backup your moodledata and the database, right?)
    $ sudo -u apache /usr/bin/php admin/cli/upgrade.php
Upgrading via command line is a very comfortable way of Moodle upgrade if you use Git checkout of the Moodle source code (see [[Git for Administrators]]). See the following procedure how to upgrade your site within several seconds to the most recent version while preserving your eventual local customizations tracked in git repository:
    $ cd /var/www/sites/moodle/htdocs/
    $ sudo -u apache /usr/bin/php admin/cli/maintenance.php --enable
    $ git pull
    $ sudo -u apache /usr/bin/php admin/cli/upgrade.php
    $ sudo -u apache /usr/bin/php admin/cli/maintenance.php --disable
== Installation ==
There are two modes of installing Moodle from the command line. In interactive mode, the install script asks you for all data needed to properly set up new Moodle site. In non-interactive mode, you must provide all required data as the script parameters and then the new site is installed silently. The parameters can be passed in the interactive mode, too. The provided values are then used as the default values during the interactive session.
    $ sudo -u apache /usr/bin/php admin/cli/install.php --lang=cs
If your arguments contain some specials characters for Linux-based systems, don't forget to ''escape'' them with a backslash. For example, if you want to create an admin with ''pa$sword'' as password you should wrote ''pa\$sword'' instead!

If required, the database install may be skipped, with just config.php populated.
   $ sudo -u apache /usr/bin/php admin/cli/install.php --skip-database
== Maintenance mode ==
To switch your site into the maintenance mode via CLI, you can use
    $ sudo -u apache /usr/bin/php admin/cli/maintenance.php --enable
To turn maintenance mode off, execute the same script with the --disable parameter:
    $ sudo -u apache /usr/bin/php admin/cli/maintenance.php --disable
If you don't want to enable maintenance mode immediately, but show a countdown to your users, execute the same script with the --enablelater parameter and the number of minutes which the countdown should run:
    $ sudo -u apache /usr/bin/php admin/cli/maintenance.php --enablelater=10
This script will also create and remove the climaintenance.html file for "Offline" mode.
== Offline mode ==
In some situations, you may want to switch your Moodle site into offline mode so that it is not accessible via the web but you can not stop the web server completely (typically because there are other web pages and applications running there). If a file called <code>climaintenance.html</code> exists in the root folder of moodledata directory, Moodle will automatically display the contents of that file instead of any other page.
    $ cd /var/www/sites/moodle/moodledata/
    $ echo '&lt;h1&gt;Sorry, maintenance in progress&lt;/h1&gt;' &gt; climaintenance.html
You can prepare a nice formatted HTML page to inform your users about the server being down and keep in the moodledata directory under a name like <code>climaintenance.off</code> and rename it to the <code>climaintenance.html</code> if needed.
== Custom site defaults ==
During the install and upgrade via CLI, Moodle sets the administration variables to the default values. You can use different defaults. See MDL-17850 for details. Shortly, all you need to do is to add a file <code>local/defaults.php</code> into your Moodle installation. The format of the file is like
<syntaxhighlight lang="php">
<?php
$defaults['pluginname']['settingname'] = 'settingvalue'; // for plugins
$defaults['moodle']['settingname'] = 'settingvalue';     // for core settings
</syntaxhighlight>
These defaults are used during install, upgrade and are also displayed as defaults on Site administration pages.
== Reset user password ==
If you happen to forget your admin password (or you want to set a password for any other user on the site), you can use reset_password.php script. The script sets the correctly salted password for the given user.
    $ sudo -u apache /usr/bin/php admin/cli/reset_password.php
==Converting InnoDB to Barracuda==
Newer versions of MySQL and MariaDB have an improved file format called Barracuda. To take advantage of this:
# Ensure your version of MySQL/MariaDB is using Barracuda with the large index key prefix (innodb_large_prefix). See below for details.
# Change to the compressed row format (see [[#Changing_tables_to_compressed_row_format|Changing tables to compressed row format]])
# Change the character set and collation for full Unicode support (see [[#Converting_character_set_and_collation|Converting character set and collation]]).


If you have MySQL 8.0.0 or later, or MariaDB 10.3.0 or later, then these versions only support Barracuda with the large index key prefix. For earlier versions to check if MySQL/MariaDB is using Barracuda run the following statement in the MySQL/MariaDB client or phpMyAdmin SQL tab:
 SHOW GLOBAL VARIABLES WHERE variable_name IN ('innodb_file_format', 'innodb_large_prefix', 'innodb_file_per_table');
If your settings do not match any of the tables below, see [[MySQL#Configure_full_UTF-8_support|Configure full UTF-8 support]] for how to change these settings:

[[File:phpMyAdmin1.png|alt=innodb_file_format=Barracuda;innodb_file_per_table=ON;innodb_large_prefix=ON]] or [[File:phpMyAdmin2.png|alt=innodb_file_format=(blank);innodb_file_per_table=ON;innodb_large_prefix=(blank)]] or [[File:phpMyAdmin3.png|alt=innodb_file_per_table=ON]]

If your settings match one of these tables then MySQL/MariaDB is using Barracuda with the large index key prefix.
===Changing tables to compressed row format===
This script changes tables with many text columns to use ROW_FORMAT=COMPRESSED. This change isn’t required but is recommended. If the database error ''Row size too large (> 8126)'' occurs when using Moodle then run this script to fix this.

'''Note:''' If you have MariaDB version 10.6.0 to 10.6.6 or version 10.7.0 to 10.7.2 you must upgrade to a later version before running this script. See MDL-72131 for details.

To view tables requiring conversion, use the --list option:
 $ php admin/cli/mysql_compressed_rows.php --list
Here is an example output:
 mdl_data                            Compact     (needs fixing) 
 mdl_data_fields                     Compact     (needs fixing)
 mdl_enrol_paypal                    Compact     (needs fixing)
To proceed with the conversion, run the command using the fix option:
 $ php admin/cli/mysql_compressed_rows.php --fix
Successful table conversion will be reported in the output, for example:
 mdl_data                   ... Compressed
 mdl_data_fields            ... Compressed
 mdl_enrol_paypal           ... Compressed
If you get errors due to having insufficient privileges to run these commands use --showsql to generate the required SQL commands:
 $ php admin/cli/mysql_compressed_rows.php --showsql
You can then copy the generated SQL into your MySQL/MariaDB client running as the 'root' user.
===Converting character set and collation===
This script changes the Moodle database tables to enable full Unicode support.
 $ php admin/cli/mysql_collation.php --collation=utf8mb4_unicode_ci
After making this change edit config.php and change the 'dbcollation' to 'utf8mb4_unicode_ci' in the $CFG->dboptions array.

For further details see: [[MySQL_full_unicode_support|MySQL full unicode support]]
== Running cron via command line ==
In versions 1.x, you could execute admin/cron.php either from command line or via the web. Since Moodle 2.0, only admin/cli/cron.php script can be run via command line.
== Scheduled tasks ==
Scheduled tasks are automatically run by the cron script, but the specific tasks which run on each cron iteration are determined by the scheduled tasks configuration. It is possible to override the scheduled tasks configuration and run a single scheduled task immediately using the admin/cli/scheduled_task.php script. 

This script accepts the following arguments:
 --list - list all the known scheduled tasks. The tasks are listed by the class name used to run the task. This class name is required as the argument to the next option in order to run a specific task immediately.

 --execute=<task> - Runs a single scheduled task immediately - regardless of scheduling settings. This will even run disabled tasks. Tasks will still use locking to prevent concurrent execution of the same task - even on clusters. The format of the <task> argument must be the same as returned by the --list option above.

 --disable=<task> - Disables a single scheduled task. The format of the <task> argument must be the same as returned by the --list option above.

 --enable=<task> - Enables a single scheduled task. The format of the <task> argument must be the same as returned by the --list option above.

 --showsql - Shows sql queries before they are execute

 --showdebugging - Shows developer debugging info
'''Note:''' You must escape the "\" with an extra \ when using the --execute command. Take the following for example:
<pre>php admin/cli/scheduled_task.php --list</pre>
will return something like:
<pre>
== List of scheduled tasks (http://yourserver.com/moodle) ==
\enrol_imsenterprise\task\cron_task                10 * * * * *      ASAP
\logstore_legacy\task\cleanup_task                 * 5 * * * *       ASAP
\logstore_standard\task\cleanup_task               * 4 * * * *       Wednesday, November 12, 2014, 4:35 AM
\mod_forum\task\cron_task                          * * * * * *       ASAP
\core\task\automated_backup_task                   50 * * * * *      ASAP

...
</pre>
To run the first task in that list, you would execute
 php admin/cli/scheduled_task.php --execute='\enrol_imsenterprise\task\cron_task'
Be aware of the single quotes. Without them, you would need to use double backlashes to avoid escaping by the shell.
=== Ad hoc tasks ===
[[Cron#Low_latency_adhoc_tasks|Ad hoc tasks]] are low-latency tasks that are normally run by the cron. You can run just the queued ad hoc tasks with admin/cli/adhoc_task.php.

This script accepts the following options and arguments:
<pre>
 -h, --help                Print out this help
     --showsql             Show sql queries before they are executed
     --showdebugging       Show developer level debugging information
 -e, --execute             Run all queued adhoc tasks
 -k, --keep-alive=N        Keep this script alive for N seconds and poll for new adhoc tasks
 -i  --ignorelimits        Ignore task_adhoc_concurrency_limit and task_adhoc_max_runtime limits
 -f, --force               Run even if cron is disabled
</pre>
For example to run the currently queued ad hoc tasks:
 sudo -u apache php admin/cli/adhoc_task.php -e

See also the improvements to ad hoc tasks in [[Scheduled_tasks#Ad_hoc_tasks]]

==Database transfer==
A command line script for [[Database transfer]] may be found in ''admin/tool/dbtransfer/cli/migrate.php''.
==Purge caches==
You can purge caches using this script:
  php admin/cli/purge_caches.php
==Kill all sessions==
If needed for administrative reasons, you can kill all user sessions using this script:
 php admin/cli/kill_all_sessions.php
As a result, all users will be logged out from Moodle.
==Backup and restore of large courses==
See Backup via CLI in [[Course backup]] and Restore via CLI in [[Course restore]] (new in 3.10 onwards).
==Fix course / module sequences==
In rare cases (such as after upgrading from a very old version of Moodle), the course / section / module sequence data can be out of sync. This can cause various problems for affected courses, such as sections not appearing, backups failing, pages not displaying etc. There is a specific check to check for errors caused by this problem, and to fix the data in the database if they are found. To run this script please use the command below:
  php admin/cli/fix_course_sequence.php -c=* --fix
This will check every course in Moodle and report which ones had errors and were fixed.
==Fix orphaned question categories==
When a quiz is created, a new question category for the quiz is automatically created. In versions of Moodle prior to 2.9.1, if the quiz is deleted, the question category and any questions in the category remain in database. These orphaned question categories may be fixed by running the admin/cli/fix_orphaned_question_categories.php script with the --fix option.
==Search and replace text==
This script can be used to search and replace text throughout the whole database. Use carefully and backup first always. More info in [[Search and replace tool]].
  php admin/tool/replace/cli/replace.php --search=//oldsitehost --replace=//newsitehost
==Build theme CSS cache==
If Moodle is not running in theme designer mode it will keep a copy of the compiled CSS on local disk and serve that to the browser when it requests a page. If there isn't a copy on local disk then a copy will be built the first time a page within Moodle is requested. 

With this script you can pre-compile the cached CSS files for themes within Moodle to avoid having a user wait for the theme to compile during the first page request.
  php admin/cli/build_theme_css.php --themes=boost
==Get and set configuration values==
Displays the current value of the given setting, or set the given setting to the specified value.
 $ php admin/cli/cfg.php [--component=<componentname>] [--json] [--shell-arg]
 $ php admin/cli/cfg.php --name=<configname> [--component=<componentname>] [--shell-arg] [--no-eol]
 $ php admin/cli/cfg.php --name=<configname> [--component=<componentname>] --set=<value>
 $ php admin/cli/cfg.php --name=<configname> [--component=<componentname>] --unset
 $ php admin/cli/cfg.php [--help|-h]
Examples:
 $ php admin/cli/cfg.php --name=langmenu
will display the value of ''Display language menu'' in ''Site administration > Language > Language settings'' (0 for ''No'' or 1 for ''Yes'').
 $ php cfg.php --name=maxsizetodownload --component=folder
will display the value of ''Maximum folder download size (MB)'' accessible from ''Site administration > Plugins > Activity modules > Folder''.
 $ php admin/cli/cfg.php --name=langmenu --set=0
will disable the ''Language menu''.
==E-mail flag for users== 
'''New in 4.2''' 
The CLI script to change the email flag for one or many users at a time can be found on the page [[E-Mail flag for users]]

== Dashboard reset ==
If you make changes to the dashboard and want all users to have their dashboard reset to reflect the changes this can be done on the cli:
 php admin/cli/dashboard_reset.php -e

== Managing plugins via command line ==
=== List and uninstall Moodle plugins ===
Moodle includes a handy command-line tool to display a list of plugins and remove plugins.
 $ php admin/cli/uninstall_plugins.php
This command line tool accepts the following arguments.

Options:
     -h --help                   Print this help.
     --show-all                  Displays a list of all installed plugins.
     --show-contrib              Displays a list of all third-party installed plugins.
     --show-missing              Displays a list of plugins missing from disk.
     --purge-missing             Uninstall all missing from disk plugins.
     --plugins=<plugin name>     A comma separated list of plugins to be uninstalled. E.g. mod_assign,mod_forum
     --run                       Execute uninstall. If this option is not set, then the script will be run in a dry mode.
     --showsql                   Show sql queries before they are executed.
     --showdebugging             Show developer level debugging information.
Dry Mode does everything the script would normally do except for actually making any changes. This is useful when you want to test the validity of your command.

Run this command from the Moodle wwwroot directory. Here are some examples:
     # php admin/cli/uninstall_plugins.php  --show-all
        Prints tab-separated list of all installed plugins.
     # php admin/cli/uninstall_plugins.php  --show-contrib
        Prints tab-separated list of all third-party installed plugins.
     # php admin/cli/uninstall_plugins.php  --show-missing
<blockquote>        Prints tab-separated list of all missing from disk plugins.</blockquote>
     # php admin/cli/uninstall_plugins.php  --purge-missing
        A dry run of uninstalling all missing plugins. This will NOT uninstall the plugin. To actually uninstall, you need to add the '--run' arguments.
     # php admin/cli/uninstall_plugins.php  --purge-missing --run
        Run uninstall of all missing plugins.
     # php admin/cli/uninstall_plugins.php  --plugins=mod_assign,mod_forum
        A dry run of uninstalling mod_assign and mod_forum plugins. This will NOT uninstall the plugin. To actually uninstall, you need to add the '--run' arguments.
     # php admin/cli/uninstall_plugins.php  --plugins=mod_assign,mod_forum --run
        Run uninstall for mod_assign and mod_forum plugins.

This tool does not perform all of the steps needed to fully uninstall a plugin. You must then:
* Remove the files belonging to the plugin manually;
* [[Administration via command line#Upgrading|Update the Moodle database]] as previously described.
If you skip one or both of these steps, you will be prompted to update the Moodle database or re-install the plugin the next time you log in as a site administrator and access the Site Administration > Notifications page.
