Rename all .jpeg and .JPG files to have .jpg extension

rename 's/\.jpe?g$/.jpg/i' *
the "i" controls case sensitiveness. It's slightly inefficient since it uselessly renames .jpg to .jpg, but that's more than compensated by launching only one process instead of two, besides being shorter to write.

What Others Think

This is "perl rename" as in it uses a perl-style regular expression to specify the search and replacement. On many linux systems 'rename' is actually a symlink to /usr/bin/prename reflecting this. There is also a more rudimentary rename command on most linux systems (from the util-linux package and invoked as rename.ul at least under ubuntu) which would do the simple renaming you're doing here: rename.ul .JPG .jpg *.JPG
