[Samba] Unwanted case sensitivity

[Kevin Keane]

First of all, Windows actually is case sensitive, too (at least on NTFS, not on FAT). You can actually create C:\tmp\foo and C:\tmp\Foo at the same time, just not in Explorer (or though most standard Windows APIs).

Secondly, even with case sensitive = No , Samba is not truly case insensitive (neither is Windows). Samba is case PRESERVING. File names do have case, Samba simply prevents creating files that differ only in case.

The case insensitivity is primarily implemented on the client side. And that's probably why you see the phenomenon: ls is built into bash (or whatever shell you are using). Sum isn't. Also, my guess is that sum /XXXX.SMB/aaabbb/fre?.txt will work as well - because the wildcard is expanded by your shell before handing it to sum.

What you could do to solve this on the Linux side:

sum $(ls /XXXX.SMB/AAAbbb/Fred.txt)

That takes advantage of bash's understanding of case insensitivity even for other programs that don't natively understand it.
