Rename files in batch

Typing the current date ( or any string ) via a shortcut as if the keys had been actually typed with the hardware keyboard in any application.
That works in all softs, CLI or GUI... I don't want to waste time to all the time typing the same stuff . So, I have that command in my window manager shortcuts ( meta+l ). All the window managers have editable shortcuts AFAIK. If not, or you don't want to use it that way, you can easily use the xbindkeys soft. I you're using kde4, you can run : $ systemsettings then open "inputs actions" and create a new shortcut. For Gnome take a look there : http://www.cyberciti.biz/faq/howto-create-keyboard-shortcuts-in-gnome/ A more advanced one, with strings and newlines : $ xvkbd -xsendevent -text "---8

Generat a Random MAC address
Original author unknown (I believe off of a wifi hacking forum). Used in conjuction with ifconfig and cron.. can be handy (especially spoofing AP's)

Router discovery

"find . -type d -print0 | xargs -0 chmod 755" thanks masterofdisaster
