This will change all files ending in .JPG to .jpg and will work with any file extension

What others think

It seems, after poking around under ubuntu, if you have perl installed, invoking 'rename' will actually invoke a perl script intended to improve on the behavior of the 'normal' rename utility provided by util-linux-ng, and typing the command as listed above will result in a weird error. To invoke the non-perl version (I've only checked under ubuntu), try

rename.ul .JPG .jpg *.JPG

To more permanently restore the non-perl rename, edit the symbolic link /etc/alternatives/rename to point to /usr/bin/rename.ul

to rename *.JPG or JpG or jPg and so... to *.jpg

rename 'y/A-Z/a-z/' *.[jJ][pP][gG]

@ bwoodacre

'which rename' will tell you the location, so you can call it like this:

/usr/bin/rename .JPG .jpg *.JPG

That's why you should use full paths if you want to make the scripts portable.
