The -f says lower case characters into the equivalent upper case, and the -d says Sort in `phone directory' order: ignore all characters except letters, digits, and blanks. Using any LANG setting other ``C'' can cause some very strange results when one is doing system administration things where I expect a straight ascii sort.
The first time I ran into this was when I was building gawk on a UnixWare system when it failed the tests because sorts weren't producing the expected results.
