Have you tried Russel's elegantly minimalist solution? Just trying the first action on the command line: $ n="01032017(001).jpg" $ echo $(echo $n|cut -c 5-8)$(echo $n|cut -c 3-4)$(echo $n|cut -c 1-2) gives a very fine: 20170301 The "(001).jpg" is added in the third line. If time is short, and mental energy drained by other demands, then KISS is key, so you can gain a quick success, I figure. (This one isn't a task which needs later upscaling.) Erik
