listen to an offensive fortune
or replace "espeak" with "festival --tts" if you like festival better when your buddy leaves his computer unlocked use "crontab" or "at" to play at some time that would be most embarassing (during his next sales presentation) $ echo "fortune -o | espeak" | at now + 30 minutes of course you can exclude the "-o" for non offensive fortunes, or if you don't have offensive fortunes installed

Quick command line math
expr will give you a quick way to do basic math from the CLI. Make sure you escape things like * and leave a space between operators and digits.

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Archive all folders in a directory into their own tar.bz2 file
Remove the "echo" to actually archive. Many similar commands are found on commandlinefu but I end up needing this very specific one from time to time. To extract any of them, use the standard tar.bz2 extract command: $tar xvjf folder1.tar.bz2

Get the IP of the host your coming from when logged in remotely
Even faster without the need for cut... :)

Random IPv4 address

Real time satellite wheather wallpaper
Changes the wallpaper to the last satellite image. Tha url above shows latin america. Seek the best url for your location Now I have a usefull background image in my desktop I use it inside kalarm updating every 15 minutes. May be done with 'watch' instead It s an option to xplanet ( kde ) and xearth needs xli , curl

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.

Watch contents of a file grow
In this case, I'm keeping an eye on /var/log/messages, but of course any file will do. When I'm following a file, I generally don't want to see anything other than what has been added due to the command or service I've executed. This keeps everything clean and tidy for troubleshooting.

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"
