== Contents of a debian file ==
To get the contents of the file "abc.deb", you have to enter
$ dpkg-deb -c abc.deb

== Reconfiguring of debconf ==
To reconfigure debconf, so that it informs you of most changes of the new packages, you have to enter
# dpkg-reconfigure debconf
Chose "medium" here

== Package Management with apt-get and dpkg ==
=== Package resource list for APT ===
The file /etc/apt/sources.list is the definition file of the sources for apt. For further information about this file type
man 5 sources.list
Retrieve new lists of packages:
To fetch the new lists of all the packages from sources.list enter as root
# apt-get update
This command checks for new release-files on the given servers. Luckily the command is clever enough to check if the release-file has changed after the last update.
Upgrade of all the files:
To make an update of all the changed packages, enter the line
# apt-get update -u
The additional flag -u shows a list of upgraded packages as well. If you want to run the update in a cron-job, you should use the flags -dy. With this flags the new packages will be downloaded but not installed. You can install them later by writing apt-get update -u.
Distribution Upgrade of all the files:
To make an upgrade of your actual distribution (e.g from potato to woody or when using unstable) replace upgrade with dist-upgrade when entering your command. So you have to type
apt-get dist-upgrade -dy
apt-get dist-upgrade -u
for an distribution upgrade.
Add a package:
How can you add a package to your system without the gui-programms? All you have to do is find out the name of this package and enter the command
apt-get install sylpheed-claws
to add the package sylpheed-claws.
Remove a package:
To get rid of the package foo which is no longer needed, enter the command
# apt-get remove foo
If the package is needed by other packages you will be prompted to remove this package and all packages which depend on it.
Forced removing of a package:
While making an distibution upgrade it coud happen that you have to remove a package first. But sometimes this is not possible with apt-get remove since the package has unmet dependencies or is not installed completely. You can remove the package foo by using the command
dpkg --force-all --remove foo
Read the contents of a installed package:
Sometimes you wan't to know which files are in the package foo. To get this information enter the command
dpkg -L foo
Get the description of a package:
You don't know what the package foo is for? Just write
dpkg -p foo
Search the package of a file:
Have you ever wondered to which package belongs a given file? To get this information (e.g. for /usr/bin/apt-get), start the command
dpkg -S /usr/bin/apt-get
and it will tell you that this file is part of the package apt.
