SSH Command Execution Hangs, although interactive shell functions fine

Question

When I attempt to execute a command on a remote server with ssh, the ssh command hangs after the exec request accepted debug message, and eventually times out.<

Answer 1

I eventually found the "$-" var which works for me:

if [[ $- =~ i ]] ; then
    [ -x /bin/tcsh ] && exec /bin/tcsh
    # Bash startup stuff goes here...
fi
