  egrep
       
          An extended version of the {Unix} command {grep}.  Egrep
          accepts extended {regular expression}s (RE) including "*"
          following multi-character REs; "+" (one or more matches); "?"
          (zero or one matches); "|" separating two REs matches either.
          REs may be bracketed with ().  Despite its additional
          complexity, egrep is usually faster that {fgrep} or {grep}.
