Ian Smith brought to my attention that I got the logic
reversed in the if statement.  He suggested to reverse
(i.e. undo) the negation, which is much better.
Thanks Ian!

     if [ -n "$SHELL" -a -x "$jail_path/$SHELL" ]; then
             login_shell="$SHELL"
     else
             login_shell="/bin/sh"
     fi

That seems to be useful indeed.  I'll have a closer look
and possibly integrate it back into my jps.  Thanks!

Best regards
