>Steven! See my problem has been solved even though I posted in hp forums.

You may be confused. This thread was moved to Linux and then Stuart answered. ;-)

>when I did #/usr/bin/ksh --version, it says bad option. I also assume ksh is corrupted.

That didn't work for me either. I got the version in vi editing mode when I typed control-V.

Thank you Dennis! I didn't know this was moved to Linux. Thanks anyways...

Staurt! How can I install ksh on my Linux node???

Not all Korn shells are created equal. Many Linux distributions ship pdksh as a Korn shell. pdksh implements KSH88, but I don't think it's even a fully-compatible implementation of that. Several years ago AT&T released the code for their KSH93 and some Linux systems now use that instead, others don't because of the AT&T license.

I think most current UNIX platforms use KSH93, but there may still be a few KSH88 holdouts. If you want a Korn shell that will be just like the one on a modern commercial UNIX system you're almost certainly better off with the AT&T version instead of pdksh.
