Well, that may or may not be true... but you don't have any regular
expressions in that command.

In any case, it looks like you are doing something on a most bizarre
operating system, such as MS-DOS, using a modified version of bash
that supports '/' as a command switch instead of '-', and with a '/S'
option that I've never heard of before.

What does "does not like it" mean, exactly?  What error are you getting?

So we don't know what command you were running, and we don't know what
it did, and we don't know what you *expected* it to do.

"Does not work"...?  Well, if I run that command inside bash on Unix, then
I would expect it to show me a literal file named '*' inside a
subdirectory named 'SomeDir'.  If there is no literal file named '*' then
I would expect ls to tell me that there is no such file or directory.

What did YOU expect it to do?  What did it ACTUALLY do?

What do you WANT it to do?

Also, in what environment are you doing this?  It is clearly not the
normal Unix environment, and so you should at least tell us what it is,
and tell us about this customized bash you're using.  Otherwise, it's
going to be extremely difficult for us to guess what all those weird
things mean.
