Hi Peter,
Thanks for your reply.
I keep on waiting for your reply.
Well, I just tried running from ksh shell too. I got the same issue.
This is what I did, I typed `which $SHELL` that returned me /bin/sh which means it's bash.
On my old shell I typed "ksh".
And then tried to execute the same script.
Now the point is, even if I typed ksh and the shell changed, but when I tried to run `which $SHELL` that returned me the same /bin/sh.
Do I have to set some path or something to point to ksh shell.
Thanks for your help. Much appreciated.
