Use lynx to run repeating website actions
This command will tell lynx to read keystrokes from the specified file - which can be used in a cronjob to auto-login on websites that give you points for logging in once a day *cough cough* (which is why I used -accept_all_cookies). For creating your keystroke file, use: $ lynx -cmd_log yourfile

opens a new session with video stream

convert ascii string to hex
Even adds a newline.

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.

Perform sed substitution on all but the last line of input
In this simple example the command will add a comma to the end of every line except the last. I found this really useful when programatically constructing sql scripts. See sample output for example.

Run the Firefox Profile Manager
even when another instance is already open. Great for testing purposes when you need to be 2 people at once on the same site.

Recover resolution when a fullscreen program crashes and you're stuck with a tiny X resolution
This forces X back to its maximum resolution configured. To get a list, type `xrandr'.

backup local MySQL database into a folder and removes older then 5 days backups
