Rename multiple files, groups of files

        1) rename -- Debian version and RedHat version differ, q.v.
           (try package util-linux:
           http://en.wikipedia.org/wiki/Util-linux)

        2) ren -- RedHat relatives

        3) renameutils -- package contains qmv, imv, icp, qcp, and deurlname

        4) mved -- (circa 2006; good as of 2015.05), perl
           http://raf.org/mved/
           (An earlier shell version may be available.)

        5) rename -- perl builtin library routine (DIY)

        6) mmv -- move/rename/copy/append/link multiple files by wildcard patterns

        7) gprename - batch rename using a GUI

        8) krename - batch rename using a GUI
