Check These Out

Show number of NIC's, ports per nic and PCI address

Ignore a directory in SVN, permanently
This command allow you to ignore certain directories on SVN commands, like SVN STATUS. It is sad see a lot of temporary files from templates_c for each "svn status", no? ;-) This works only on directories under revision control.

Display the definition of a shell function
Display the code of a previously defined shell function.

Check syntax of all Perl modules or scripts underneath the current directory
Finds all *.p[ml]-files and runs a perl -c on them, checking whether Perl thinks they are syntactically correct

Find the package that installed a command

Re-use the previous command output
The $(!!) will expand to the previous command output (by re-running the command), which becomes the parameter of the new command newcommand.

get a fresh commandlinefu-item each day as motd
Commandline-fu often has little tricks that I always forget. By adding this to the root-cron (sudo crontab -e) I lean a new trick every day.

Eliminate dead symlinks interactively in /usr/ recursevely
Its not mine... I get from textlive migration in gentoo : http://www.gentoo.org/proj/en/tex/texlive-migration-guide.xml

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

External IP (raw data)
can be used in script like : echo $(wget -qO- http://utils.admin-linux.fr/ip.php)
