Tasks are defined in .desc files found in /usr/share/tasksel. Debian derivatives can easily add tasks.
The default list available in Ubuntu can be viewed with this command-line:
$ sudo gedit /usr/share/tasksel/ubuntu-tasks.desc
Since Ubuntu 6.10 (Edgy) tasksel has been included as part of the base installation. Tasksel is present on all versions of Ubuntu’s installer, but previously was not installed on the base system.
To run tasksel, at the command line, type
$ sudo tasksel
the tasksel menu will be shown:
Already-installed tasks will have an asterisk beside their name. Select a task by scrolling down and pressing space. This will put an asterisk beside the selected task and mark it for installation. Removing an asterisk marks the task for removal. Once “ok” is selected the task installations and/or removals will take place using apt-get.
Command line arguments
You can also directly specify which task to install.
For instance, to add the Apache-MySQL-PHP stack to an existing system:
$ sudo tasksel install lamp-server
For complete options, see the tasksel manpage:
$ man tasksel
