Google broken again eh Geoff?

To lower-case all files in your current directory use:

for i in * ; do mv $i `echo $i | tr [A-Z] [a-z]` ; done

you may wish to use *.[Jj][Pp][Gg] to trap all the case variances of 
JPG, Jpg, jpg etc and not touch other files you might have there.

you may also wish to look up mv -i before running anything like this.

it doesn't work on files containing spaces but I have another script for 
that.

My nautilus-scripts folder contains the following which does exactly the 
same job, I use the above more often but there are times when a GUI file 
manager is handy

#!/bin/sh
# lowercase any filenames with uppercase chars
for file in $*
do
if [ -f $file ]
then
   lcfile=`echo $file | tr [:upper:] [:lower:]`
   if [ $file != $lcfile ]
   then
     mv -i $file $lcfile
   fi
fi
done


Programs such as gqview have a duplicates detection capability if you 
want to hunt them out too.


Cheers

Rick
