Judging from the behavior, it seems as though pathname expansion uses its own mechanism to determine if a file matches the wild card, not the one built into Win32 (FindFirstFile with the wild card name as a parameter). If it's not difficult to switch to using the OS wild card matching, then wouldn't this automatically give the correct behavior on a FAT/NTFS/HPFS partition AND a drive mounted from a Unix box that is case sensitive? Any ideas? >>> Richard Donkin 12/15/96 01:01pm >>> In-Reply-To: > It seems that the cygnus file and shell utilities are case sensitive when > performing wildcard expansion, and aren't for an explicit file name. > > For example, ls *.cpp will not show HELLO.CPP, but ls hello.cpp will > show it (as lower case).

One workaround is to lowercase all files - I use a perl script that goes: for $filename ( @ARGV ) { rename($filename, "\L$filename") or warn "lower: could not rename '$filename' - $!\n"; } I realise this may not always be possible - IMO Cygwin should provide an option, probably as part of mount(1), to ensure that the readdir type system calls used for wildcarding / filename completion return lower-cased filenames, when used on a filesystem that is mounted with the no-mixed option. Of course, all files on that filesystem would then appear to be lower case to ls etc. Richard -- richardd AT cix DOT compulink DOT co DOT uk http://www.inside-edge.co.uk/ Inside Edge Consultancy Client/Server and Internet Applications PGP key from: pgp-public-keys AT keys DOT pgp DOT net -or- http://www.four11.com/ - For help on using this list, send a message to "gnu-win32-request AT cygnus DOT com" with one line of text: "help".
