That's strange. I tried that and had no problem.
Here's a slightly enhanced version with more options. -h shows a help, -d
also converts directories, -r turns recursive operation on, and -u would
convert into uppercase instead. So you would use it like that:
lowercase -dr *
This assumes you also want the directory names converted. Leave the -d
option off if not. And add a -t first so you see what would be done, in
case the script would mess things up. It seems to work, but was written
rather quickly. If all seems okay, start it again without the -t.
If it still don't work, you can also use the find command to process each
file individually:
find . -exec lowercase -d \{\} \;
Or this if you like to change files only:
find . -type f -exec lowercase \{\} \;
Feel free to email me directly if you are still having trouble, so we won't
bother the list.
