Check These Out

Blink Caps Lock on HDD activity
Some computers these days don't have an HDD activity light, but they still have a useless caps-lock, so why not re-purpose that light to show HDD activity? Requires setleds and dstat and probably needs to run as root.

Search some text from all files inside a directory

gvim in full screen (execute again to toggle full screen on/off)
Only under linux. Requires Gvim compiled with "clientserver" functionality and wmctrl command installed on system. Instead of servername can be used the current edited file name. Put it in a function and map it for get rid of "Press a key" after execution.

Pretty man pages under X

Concatenates lines using sed

bash screensaver off

Resolve the "all display buffers are busy, please try later" error on a Foundry

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"

get a desktop notification from the terminal
tired of switching to the console to check if some command has finished yet? if notify-send does not work on your box try this one... e.g. rsync -av -e /usr/bin/lsh $HOME slowconnection.bar:/mnt/backup ; z (now fire up X, do something useful, get notified if this stuff has finished).

recursively walk down no more than three levels and grab any file with an extension of mp3, mpg, mpeg, or avi
