In my .profile I set "export ENV=~/.kshrc". Certainly I don't want the aliases or something to executed for non-interactive shell, i.e. the shell spawned to interprete the ksh-scripts. Is there a way to tell if the shell is interactive wone ithin .kshrc ?

If you only want to do something if you are interactive, then put the
following at the appropriate places in your $ENV file:
if [[ $- = *i* ]]
then
do stuff for interactive here
fi

You can easily see this by putting this line in a script file. Now, if I hadn't tried it, I wouldn't have suggested it! It works for me, and has worked interactively, and via a script. Now, if your standard input is altered, even by you putting the script in background (making it non-interactive) then the message won't be printed. Maybe you have a broken ksh? The one I have came with SVR3.2/68k from Motorola. As a matter of fact, it even works with the Bourne shell we have (as it should, because it's a standard test function). Can you tell me what I'm doing right? :-) -- Bernd Felsche, _--_|\ #include <std/disclaimer.h> Metapro Systems, / sale \ Fax: +61 9 472 3337 328 Albany Highway, \_.--._/ Phone: +61 9 362 9355 Victoria Park, Western Australia v Email: bernie@metapro.DIALix.oz.au
