[Malvern] One for the Perl-mongers.

[Geoff Bagley]

I have a number of .jpeg file ( photographs etc.),  and would like to 
convert the file names
of the whole lot to lower case.

Currently some are both .jpg and .JPG,  and both  img_ and  IMG_   and 
the same files are
stored more than once.   The files all come from various sources who use 
differing standards.

Storing very large files (like photos) is very wastful of space.

A quick steer to the correct page of the (RT)FM would be appreciated.

Geoff.
