View source for Template:MySQLdump Linux

Using MySQLdump in Linux is also possible, and is typically provided along with the mysql/mariadb-server installation. This is a script that can be used either manually or be hung into time-repetitive cron jobs. Log files are created with filenames that have a timestamp built-in, so older backups will not be overwritten. 
Copy the script below into your favorite text-editor and save it as a .sh (bash) file into the location+filename of your chosing, and make the file executable with <syntaxhighlight lang="bash" inline>chmod +x yourfilename.sh</syntaxhighlight>. You can export database contents for the Kodi video library, music library, and the database user for the Kodi application. You can do so separately or combined with all three parameters at the same time.

<syntaxhighlight lang="bash">

#set -x  # enable in case of trouble
