I am new to UNIX hence the question. Most of the time when I have an environment set up for me to develop my systems, I have had my ID logon and I can edit the .profile for my account and it understand commands korn shell. It seems this machine, a new SUN machine, was setup with users getting the Bourne shell as default. I get /bin/sh when I type in the command echoe $SHELL at the $ prompt. Is there anyway for me as a user to change that? How can I default my login into ksh? Is that possible?

Not directly as a normal user, however you could test the shell and exec ksh in your .profile and it should work.

Thanks, that's what I needed to know.

I read that below command can be used, but my shell do not find this command
chsh -s /usr/local/bin/bash <usename>
