I am using AIX 4.3.3 and the korn shell. I have a script that provides a
menu to our operators. When a selection is made, a set of environment
variables are set, by calling another script. For example, selection "2" I
use the case function to come to the action . /home/user/setenv1 This works
fine in the script, but when I exit, the environment reverts back to the
original state, (what it was before the menu was run). If I put that same
command in a one line script, that is, testt.sh contains .
/home/user/setenv1 This sets the environment and it stays set even when the
script is done. I'd appreciate any advice.

Hello,
well, the best advice is: Please look into the FAQ for
comp.unix.questions.

That treats this problem and many more which you might encounter some
day.

Good luck
Alois

Forgive my ignorance, but where do I find the FAQ?

Hi,

Send the script. I'll make it work.

Dotting a script and running a script are entirely separate cases.
The rule to remember is that a child cannot modify a parent's
environment. Your get-out-of-jail-free card is the "eval" command,
q.v.

If you are running a script and intend to have it change variables in
the current environment, you must 'source' it (that is,
do not
bozo
but
. /path/bozo
where the dot is 'sourcing' the file bozo.

Else, bozo runs in a subshell so things it sets are never seen at the
higher level.
