  • Unix How-To: awk is still a very handy tool

    Posted June 2, 2010 - 2:38 pm

    Awk does a lot more than select a column from a file or an input stream. It can select columns from selected rows. It can calculate totals, extract substrings, reverse the order of fields and provide a whole lot of other very handy manipulations. Whether you squeeze your awk permutations onto the command line or prefer to build them into scripts, the language is clever and versatile and well worth using even as it joins the ranks of middle-aged computer utilities.
