Run: echo [:upper:] [:lower:] and then echo "[:upper:]" "[:lower:]" in the two directories to spot the difference. (Hint - in one of your two directories, a shell glob is matching a one-byte file name) As this is user error and not a bug in tr, I'm marking this bug as closed, but feel free to add more comments if you still need help understanding the issue. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
