Hi Folks,

Not sure I'm in the right place - but - I'm having a problem with the "mv" command in Cygwin's Unix emmulator... The man page directed me to this address... I have a bunch of files that all start with the "-" character (-moo, -moo1, -moo2)... Obviously the "-" is treated as a switch in the Unix world - so you can't do simple moves as you would in Solaris... I'm not sure if the goal of your GNU release is supposed to match the functionality of Unix but I just wanted to point this out in case you were unaware...

In Solaris - this works: 
 
    mv -f - '-moo' SCO-moo

In Cygwin - it does not...

Thanks...

Regards,
Scott

two -- are need to terminate option processing in GNU land

  mv -f -- '-moo' SCO-moo

Yes, this is the right place; you'd see the same behavior on Linux,
which means it is not cygwin-specific (if you do encounter something
that you cannot reproduce on Linux, then the cygwin lists are a better
place for that question).

That behavior is not required by POSIX.  But what POSIX _does_ require
is that:

mv -f -- -moo SCO-moo

does the right thing, and GNU mv complies with that.  You can also use:

mv -f ./-moo SCO-moo


You have asked a FAQ; for more details:

Therefore, I'm closing this as not a bug, although you can continue to
respond to the thread if you have more questions on the topic.
