The world's smallest Bash tip
This is likely the briefest useful tip I’ll ever give. Sometimes you don’t want sensitive information, like a password, to be included in the history of your bash terminal. You don’t have to go to your .bash_history
file and remove it afterwards - instead you can just:
For instance:
mpjdem@mpjdem:~$ echo $HISTCONTROL
Press the up arrow to test and the above line shouldn’t show up in your history. If it does, likely the HISTCONTROL
environment variable was not set to either ignoreboth
(default) or ignorespace
. Change this in your .bashrc
if that’s the case.
