   Yes and no, sh/bash/dash is probably already in memory for some
  (many) shell-scripts. Since most of the memory is shared between
  processes (read-only memory of processes and libraries is shared),
  memory footprint won't change much whether you launch this script
  or not.

     Whether this is a sensible idea or not, I leave it to more
  knowledgeable people.
