-====== Ubuntu - Bash - Rename multiple files ======
-The **rename** command which is part of the Perl installation helps.  All you need to know is the basics of regular expressions to define how the renaming should happen.
-----
-To add a '.old' to every file in your current directory.  At the end of each expression ($) a '.old' will be set:
-<code bash>
-rename 's/$/.old' *
-</code>
-----
-To make the filenames lowercase:
-<code bash>
-rename 'tr/A-Z/a-z/' *
-</code>
-----
-To remove all double characters:
-<code bash>
-rename 'tr/a-zA-Z//s' *
-</code>
-----
-You have many JPEG files that look like “img0000154.jpg” but you want the first five zeros removed as you don’t need them:
-<code bash>
-rename 's/img00000/img/' *.jpg
-</code>
-In fact you can use any Perl operator as an argument.  The actual documentation for the 's' and 'y'/'tr' operators are found in the 'perlop' manpage.
