The point remains: Globbing is case sensitive while full command name invocation/full filename use is not. And, you may never have been confused by that, but I maintain it's very confusing. I'm not asking that it be "fixed", I'm asking that it be carefully documented, and I'm not asking anyone but me to do it. If it is so documented, I missed it. And, I read and reread that part of the manual before posting both times. I offered an example session transcript that made that perfectly clear, and I am willing to write that up however you want it. Thus far, you've made clear you don't want it. No further replies will be required if my last "read" is correct. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

If you feel up to the task, patches to the documentation are more than welcome.

This has nothing to do with Cygwin. You are (still[1]) confusing Cygwin
and your shell. You would hugely benefit from gaining some basic
knowledge about the tools you've been using since 1979.
Your transcript was done in a shell called "bash". Globbing in bash is -
by default - case sensitive. If you want to change that, read the man
page and then set option "nocaseglob" ("shopt -s nocaseglob").

The globbing is not where the confusion lies. This globbing:
$ ls xwin*
ls: cannot access xwin*: No such file or directory
works as expected and did not confuse anybody. Here's what confused
the OP:
$ ls xwin
xwin
$ ls xwIN
xwIN
This is unquestionably a normal, Cygwin specific condition, caused
by the semantics of the underlying NTFS, but very confusing to
someone whose experience is with UNIX.
This note:
http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-casesensitive
warns that you cannot have two filenames in the same directory that
differ only by case, because of NTFS semantics.
It could be improved to warn that because of NTFS semantics there
are also filenames which exist but which Cygwin's readdir() does not
return, and which therefore are truly hidden -- will never show up
in directory listings or globs.
I think this is what the OP was volunteering to do.
Cheers,
MetaEd
