Countdown Clock
The biggest advantage over atoponce's nifty original is not killing the scrollback. Written assuming bash, but shouldn't be terribly difficult to port to other shells. S should be multiple spaces, but I can't get commandlinefu to save/show them properly, any help?

Search specified $TEXT1 and Replace that by specified arg ($TEXT2)

Set laptop display brightness
Run as root. Path may vary depending on laptop model and video card (this was tested on an Acer laptop with ATI HD3200 video). $ cat /proc/acpi/video/VGA/LCD/brightness to discover the possible values for your display.

archlinux: find more commands provided by the package owning some command
uses the pkgfile command (part of the community repository), highly suggested.

Rename files in batch

Update twitter via curl (and also set the "from" bit)
An improvement of the original (at: http://www.commandlinefu.com/commands/view/2872/update-twitter-via-curl) in the sense that you see a "from cURL" under your status message instead of just a "from API" ;-) Twitter automatically links it to the cURL home page.

create and md5 sum of your password
create and md5 sum of your password without it showing up in your terminal or history. Afterwards we overwrite the $p variable (thx to bazzargh)

grep -v with multiple patterns.
You can use -e to pass multiple patterns.

Replace 'csv_file.csv' with your filename.
