According to Keith Thompson on 3/26/2008 10:56 AM:
| (I used to use just "/", but Solaris for some supremely odd reason
| allows a file "foo" to be referred to as "foo/", so I've cultivated
| the habit of using "/.".)

Yes, that's a bug in older Solaris (but should be fixed in Solaris 10).

|
| I've recently found that the "mv" command, if given a second argument
| of "nosuchdir/.", if "nosuchdir" doesn't exist, treats it as a file
| name.  I don't know whether this is specific to Cygwin or a bug in
| the current GNU coreutils.

Most likely a cygwin bug.  Similar to the cygwin bug that foo/bar/.. is
treated as foo/, even if foo/bar does not exist.  And to prove it:

$ mkdir example
$ cd example
$ touch foo
$ strace mv foo bar/. 2>&1 |grep rename
~  450  103717 [main] mv 2476 rename: 0 = rename
(c:\cygwin\tmp\example\foo, c:\cygwin\tmp\example\bar\)

That rename should have failed with ENOENT.
