Is there some reason that perl's built-in grep is less useful than starting a whole 'nother piped process?

while (1) {
  if (not grep { /soffice\.bin -quickstart/ } `ps ax`) {
    sleep 5;
    system('/usr/lib/openoffice/program/soffice.bin -quickstart -plugi
+n');
  }
}

Now you don't have to worry about the whole "grep in ps" work-around.
