Do a command but skip recording it in the bash command history

_cd ~/nsfw; mplayer midget_donkey.mpeg
Note the extra space before the command (I had to put it as an underscore since the website eats up preceding spaces). That's all it takes. Now if you check your history with "$ history", it wont show up.

This works with Opensuse 11 and midget_donkey rocks!!!

Works in Ubuntu 8.10. Upon checking the bash man page, you need the environment variable HISTCONTROL=ignoreboth or =ignorespace. My bad for not noting this. Also you can have more control by using HISTIGNORE
