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.
