Always clear last command

GUIPenguin · 09-14-2004, 04:31 PM

You know when you open a shell and click the up or down arrow it displays the last command you typed into a terminal

Is there a way or a command that could be written to clear this

Thanks, John!

If you are talking about a bash shell set the HISTSIZE to 0 (zero).

Can be found:

globaly in /etc/profile (or /etc/bashrc)
local in ~/.profile

Hope this helps.

Sure,
history -c
if you're using bash (which is pretty much default these days).

Well it migth be that I was a bit too enthusiastic

My option prevents the history entirely, the history -c options clears what's there and after that commands are added to the history again.
