6/8     Which search engines let you search for regex or at least symbols like
        '||' .  right now i'm trying to search for how to do this:
         !#/bin/bash; if [ $? != 0 || $# != 2 ]; then hi
        \_ man test
           \_ Or, sillier, man [
           \_ test did the trick, tnx.  (though, shirley there must be a way
              to do it without)
