Remove all unused kernels with apt-get
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.

Get max number of arguments
Get max number of arguments that can be accepted by the exec() system call.

Find the package that installed a command

Display the top ten running processes - sorted by memory usage
ps returns all running processes which are then sorted by the 4th field in numerical order and the top 10 are sent to STDOUT.

Iterate through current directory + all subs for C++ header files and rank by # of comments
This shows you which files are most in need of commenting (one line of output per file)

Show permissions of current directory and all directories upwards to /
NB not 'namei -m .', as it slices the path you give it.

Join lines split with backslash at the end
Joins each line that end with backslash (common way to mark line continuation in many languages) with the following one while removing the backslash.

change microdvd subtitles framerate
this command example converts to 25 fps subtitles that were originally created for 24 fps movie

Burn CD/DVD from an iso, eject disc when finished.
cdrecord -scanbus will tell you the (x,y,z) value of your cdr (for example, mine is 3,0,0)

Create subversion undo point
Allows you to save progress without committing. To revert to an undo point, svn revert then apply the undo point with patch. $ svn revert -R . && patch -p0 < .undo/2009-03-27_08:08:11rev57 Similar: http://www.commandlinefu.com/commands/view/373/archive-all-files-containing-local-changes-svn
