Never use rm -rf with wildcards… please…

Disable the usage of history using HISTSIZE

1. HISTSIZE=0
export HISTSIZE

2. Force history not to remember a particular command

export HISTCONTROL=ignorespace

3. Ignore specific commands from the history using HISTIGNORE

export HISTIGNORE=”vi:ls -alrt:ifconfig” …etc

Cheers

I created the following alias:

alias clearhist=’rm ~/.bash_history && history -c && exit’

This seems to clear everything without leaving any sort of trail…

(It was created based on this site, I must confess)

Root is right, avoid using -rf unless necessary.

The -rf is completely unnecessary, and will only break things if you typo something else in the command.

Very thorough. I though there was also a special signal like this?
killall -(something) bash
