Turn off "bash_history"

swmok · 11-30-2003, 09:02 AM

Hi all:

Every I log out the system, the system will generate a ".bash_history"
file to record down my pass command.

I would like to turn this feature off.
How?

Thanks.

in your .bashrc, try adding "export HISTFILE=/dev/null" or "unset HISTFILE", or possibly make a symlink of /dev/null to .bash_history, or change the permissions on the file to prevent writing to it.

why would you want to turn of bash_history, it's really convenient!

In case anyone else is looking for an answer to this, just type:

HISTIGNORE="*"

to turn it off, and

unset HISTIGNORE

to turn it back on again

Re: Acid_Kewpie's advice...

Code:

rm /home/$user/.bash_history
ln -sf /dev/null /home/$user/.bash_history

Why the rm if you use the -f option in the ln?

Or better yet:

Code:

echo 'shopt -u -o history' >> ~/.bashrc && exec bash

Optionally you could remove the .bash_history file before that.

I dunno, It is not my snippet, I just 'borrowed' it and never had to actually use it or read the man page until now!

Code:

--force
              remove existing destination files
