Show us the how the '.profile' calls the '.kshrc' please.

And the dumb question, the user you are logging in as has '/bin/ksh' as it's shell, yes?

Oh boy.. Bad..

Lets start with this.

NEVER LINK 'sh' TO ANYTHING OTHER THAN 'bash' ON A Linux BOX!

If you want a user to use 'ksh' as their login shell, then make the user's shell 'ksh'!

Quite a number of scripts written on a Linux box are written expecting bash functionality! 'ksh' doesn't work in the same manner as 'bash', so some unexpected things WILL happen.

Now, all that said. On a RH box by default, a '~/.kshrc' won't be called.

So this goes back to my previous question, how are you calling your '.kshrc' from your '.profile'?

Hi Stuart

'pdksh' (which is the default KSH package on a RedHat box) won't call a '~/.kshrc' on it's own.

In the user's profile (or possibly the '/etc/profile'), a section that says something like this is required:

if [ "$SHELL" = "/bin/ksh" ]
then
[ -f "~/.kshrc" ] && . ~/.kshrc
fi

This will execute a '~/.kshrc' if it exists, and the shell is 'ksh'. Using the '.' method of execution means that any environment changes which occur in the '.kshrc' is within the shell's scope, and will stay there.

Hi Stuart

I have copied .kshrc to bashrc and set the
enviromnet in the .profile and it seems to be working

export ENV=$HOME/.bashrc

Thanks for making me think

Thanks
