Check These Out

Returns true (0) if the string is into $var, or false (1) if not.

Create a 5 MB blank file via a seek hole
Similar to the original, but is much faster since it only needs to write the last byte as zero. A diff on testfile and testfile.seek will return that they are the same.

Search and replace in multiple files recursively

Stream (almost) any music track in mplayer
Just give it an artist and/or song at the end of the command as shown.

Matrix Style
It's the same command as submitted, but first with a command to make all characters green. It's the only way it looked "matrix-like" on my gnome-terminal.

relabel current konsole tab
usage: renam in a script you must replace $PPID with $(awk '{print $4}' /prod/$PPID/stat)
