Rename files in batch

bulk rename files with sed, one-liner

Far from my favorite, but works in sh and with an old sed that doesn't support '-E'

Programmatic way to find and set your timezone

Create a new file

Opens files containing search term in vim with search term highlighted

Takes the same arguments that ack does. E.g. ack-open -i "searchterm" opens all files below the current directory containing the search term. The search term is also highlighted within vim if you have hlsearch set. Works on zsh, unsure if it works on bash. Note: ubuntu users have to change ack to ack-grep unless you already have it aliased (as I do)

Displays the version of the Adobe Flash plugin installed

This is for Debian, simply change the path if your Flash plugin is installed elsewhere.

Poor's man Matrix script

This creates a matrix of letters that run forever until you hit Ctrl-C simulating "The Matrix" effect... just for fun :) You may want to try the -n and -y switch to change the "FX" LOL! e.g.: pwgen -ny 3
