Removes packages that are recommended by other packages.
Shows the packages installed on your system that are recomemnded by other packages. You should remove these packages.
locating packages held back, such as with "aptitude hold "
small update for this command to work with linux kernels 3.x
Marks all manually installed deb packages as automatically installed. Usefull to combine with
apt-get install <all manually packages that we want>
to have a clean installed debian-based system.
This will print the name of every installed package on a Debian system.
since awk was already there one can use it instead of the 2 greps. might not be faster, but fast enough
Especially useful for latex packages, which are listed in the description of their Ubuntu package E.g. say I want to find the Ubuntu package containing latex package aeguill:
aptitude search ~daeguill
p texlive-lang-french - TeX Live: French
This is the best way I have found to search out an application when I am not sure the title.
Grep is just to remove anything that does not contain the term in the title or short description (lots of things might include the search term in the description, such as libraries used by the application)
Replace PACKAGE with desired package name.

Same as 7272 but that one was too dangerous
so i added -P to prompt users to continue or cancel
Note the double space: "...^ii␣␣linux-image-2..."
Like 5813, but fixes two bugs: [1]This leaves the meta-packages 'linux-headers-generic' and 'linux-image-generic' alone so that automatic upgrades work correctly in the future. [2]Kernels newer than the currently running one are left alone (this can happen if you didn't reboot after installing a new kernel).

I'm bummed that this took 228 characters. I'd like to see a simpler version.
Lists all packages in "rc" state and purge them one at a time.
also search with aptitude search '~c'
A little aptitude magic. Note: this will remove images AND headers. If you just want to remove images: aptitude remove ?and(~i~nlinux-im ?not(~n`uname -r`))
I used this in zsh without any problems. I'm not sure how other shells will interpret some of the special characters used in the aptitude search terms. Use -s to simulate.
This should do the same thing and is about 70 chars shorter.
Very handy if you have done a package selection mistake in aptitude.
Note that it's better to do a Ctrl+U (undo) in aptitude if possible, because the keep-all will clear some package states (like the 'hold' state).
The legend in the first column:
i = installed
p = installable
