Humm, 'grep' is a filter, i.e. something that removes parts of the data being perused, while this case it will not filter anything, it will just make something that matches some search criteria to stand out from the rest, that is still there, so perhaps --emphasize is Ok albeit kinda long... Do we have any other command line tool that has a long standing semantics of "highlighting" or "emphasizing" parts of a data stream? - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
