execute:
cd /path/to/folder; ls -al | grep JPG | awk '{print $9, $9}' >shit && vi shit
in vi hit escape, delete the top two lines (should be "." and "..", these can be deleted by hitting "d" twice, followed by shift-colon, at the colon prompt enter this sequence:
%s/^/mv /g
enter after that, simply change the second colum to have lower case jpg at the end. escape back to shell and save by hitting escape shift-colon and at the prompt enter:
wq!
at the prompt execute:
sh shit
I would explain how to do it for all files etc... but that's getting a bit tricky and wouldnt want to do so without seeing the file structure myself. be careful!
