I believe you are running two commands.  The first is invoking
tcsh with no arguments and it immediately returns.  I believe it
returns because a non-interactive shell executes either the
command supplied by -c or the filename supplied.  Once all
commands are exhausted the shell quits.

    How do I run my command with a shell other than sh?
