.sh_history size

[KenCunningham]

Hi folks, hopefully a quickie - how does one change the number of commands to be stored in the .sh_history file in AIX 5.2. I had thought it might be the $HISTSIZE variable, but this is related to password reuse. TIA.

Hi Ken,

I agree with you on it being the HISTSIZE env var, but cant be sure at 5.2. Its is definately the case at 4.3 and 5.1 so I would think it would be the same for 5.2.

One interesting aspect of its use under AIX is that it seems to allocate storage based off this var on execution of ksh (ie. it does not look like its dynamic).

This means that you will not see the affects of your change within the current shell. If you run ksh again though (after exporting your HISTSIZE var) you should see your change manifest.

If someone knows how to alter this characteristic within your current shell (in AIX) .... I'd be very interested to hear it ;-)

All the Best Bud

Thanks pal, I think maybe I was confusing histsize and HISTSIZE. I've got a test system I can play on, so I'll see what happens when I change it. Have a good weekend!

d3vzero,

While technically not the current shell (it overlays the current shell, but keeps the environment), this should effectively be the same:

export HISTSIZE=2048
exec /bin/ksh

LOL,

Yeah .... Thats how I got around it too

It is kind of weird that the attribute was not built to be dynamic in the first place though.

BRgds.
