First of all, thanks for all of the inputs and valueable advices.

I guess Jhwilliams is correct, something is messed with my shell on this server b/c the same script is working on another server. The only thing different is this server is Linux and the other one in Solaris. Rather than fixing the code, I think it's best for me to find out what's going with the shell on this server.

Any advices for me to find out what's going on with this server?

Thanks all,

@brian, actually, catkin has it. the prefixed - comes from login. If you run the code in a pseudo-terminal, it disappears. Replacing $0 with ${0#-} is a fine solution to the problem. Nothing wrong with your shell, I take it back.

So this is just a login shell.
Except for the csh I think all shells show a "-" before.

man bash | grep -A3 -E -e  '^INVOCATION$'
