Get all IPs via ifconfig
and, a lot uglier, with sed: $ ifconfig | sed -n '/inet addr:/s/[^:]\+:\(\S\+\).*/\1/p' Edit: Wanted to be shorter than the perl version. Still think that the perl version is the best..

Using ASCII Art output on MPlayer
Not so useful. Just a cool feature.

auto terminal title change
above line in .bash_profile will give you window title in putty or terminal client when you login to your remote server

Find the 20 biggest directories on the current filesystem
This command will tell you the 20 biggest directories starting from your working directory and skips directories on other filesystems. Useful for resolving disk space issues.

Updating to Fedora 11

Tail a log-file over the network
it also works with the chrome browser. The alternative with tail and nc doesn't

Search for a line of text in a directory of files recursively (while limiting to certain file extensions)

Localize provenance of current established connections
Sample command to obtain a list of geographic localization for established connections, extracted from netstat. Need geoiplookup command ( part of geoip package under CentOS)

List only the directories
This command would be useful when it is desirable to list only the directories. 'egrep' chooses only the lines that begin with 'd'.

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"
