Prepend a text to a file.
Syntax: $ prepend content to add [filename] Uses ed, so no temp files created.

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

Live filter a log file using grep and show x# of lines above and below

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"

list your device drivers
great for running off a bootable cd to identify hardware other os's can't detect

Change MySQL Pager For Nicer Output

Watch the size of a directory using figlet
You can substitute /home/$USER with any path you like.

Monitor a file with tail with timestamps added
This is useful when watching a log file that does not contain timestamps itself. If the file already has content when starting the command, the first lines will have the "wrong" timestamp when the command was started and not when the lines were originally written.

Schedule a command while one is already running.
Useful when you have only one terminal session e.g. ssh. and want to queue up another command after the currently running has finished(in case if you forget to run that command). Originally used as ; python-updater when running emerge. When I have noticed that a package failed due to that command not run.
