I found this in the ubuntu documentation. Tasksel is an installation system that is an integral part of the Debian installer; it is also included in Ubuntu. Tasksel groups software packages by tasks and offers an easy way to install all the packages needed for that task. It provides the same functionality as using conventional meta-packages. Tasks List 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 Installation 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. Usage 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...

This article will show how you can  rebuild any debian package . You might need to rebuild a package for various reasons: add/remove some compilation options, make some changes to the sources, or compile a newer version from testing/sid into stable, etc. Regardless of your reason, this can be done very easy using debian tools. First you will need to have some basic debian building tools installed: apt-get install devscripts build-essential 1. Get the source package Debian repositories contain the  sources  for all existing  debian packages . In order to get a source package you will need to have in your  /etc/apt/sources.list  a  deb-src  line (this is exactly as a regular  deb  repository line, but it is for sources). This will look like: deb-src http://ftp.us.debian.org/debian/ etch main non-free contrib change it accordingly to your needs (a close mirror, testing or sid instead of etch, and so on). Once you have your sources file updated refresh your packages lists: apt-get update N...

In technical terms, kill simply sends a signal. By default it sends a signal which requests termination ( TERM , or signal 15); but you can also specify a signal, and signal 9 ( KILL ) is the signal which forces termination. The command name kill is not necessarily appropriate to the signal sent; for example, sending the TSTP (terminal stop) signal suspends the process but allows it to be continued later. kill %1 - means Kill off job 1. Bash will report the job information: $ kill %1 [1]- Terminated man cp $ Bash is only asking the job to quit, and sometimes a job will not want to do so. If the job doesn't terminate, you can add the -9 option to kill to stop asking and start demanding. For example: $ kill -9 %1 [1]- Killed man mv $ The -9 option forcibly and unconditionally kills off the job.
