-noshell
       Available only for qrsh with a command line.

       Do  not  start  the command line given to qrsh in a user's login
       shell, i.e.  execute it without the wrapping shell.

       This option can be used to speed up execution as some  overhead,
       like the shell startup and sourcing the shell resource files, is
       avoided.

       This option can only be used if no shell-specific  command  line
       parsing  is  required. If the command line contains shell syntax
       like environment variable  substitution  or  (back)  quoting,  a
       shell  must  be  started.   In  this case, either do not use the
       -noshell option or include the shell call in the command line.

       Example:
       qrsh echo '$HOSTNAME'
       Alternative call with the -noshell option
       qrsh -noshell /bin/tcsh -f -c 'echo $HOSTNAME'
