Anyone know how to increase bash's history length? I've done it before, I think it's a variable, but I can't figure it out today. Also, how do you show all of your shell variables? I know it can be done but I forget the command. ---------------------------------------------------- Jonathan Wilson System Administrator Cedar Creek Software http://www.cedarcreeksoftware.com Central Texas IT http://www.centraltexasit.com

HISTSIZE=<some number> HISTFILESIZE=<some number>

shopt -p will show some options, but I don't know how you would go about displaying all of the shell variables. - v -- Victor R. Cardona vcardona@home.com "Behold the keyboard of Kahless, the greatest Klingon code warrior that ever lived!"
The variable you want is called HISTSIZE. It's default is 500 commands -
probably a bit excessive for most people :)
You can get details of a single variable with the command
echo "$variable-name"
for example on my machine
fogg $ echo "$HISTSIZE"
500
fogg $
You can get a list of variables and their values by just typing 'set'. On my
machine ther are over 80 of them, so I'd advise using
set | less
