Confirmed. Unfortunately, this is a side effect of my improvements to ln to unify the cygwin-specific .exe code which tries to determine when the original file exists as just "file" vs. "file.exe". Inside normal directories, the test is simple - check if "file." exists (since Windows flattens the trailing .). But for virtual filenames (such as /cygdrive, /proc/registry, //server, or managed drives), the trailing . trick doesn't work. I really NEED a way to tell whether a file exists with exact spelling, or had .exe appended, and you've found a place where the trailing . trick is not cutting it. Since ln, mv, and cp share my cygwin-specific code now, I imagine it is probably easy to find a similar bug in cp or mv. Is there an easy way to tell if a filename resolves to a virtual mount, instead of a disk file, and therefore know that the trailing . trick won't work? > Where it doesn't (e.g. it isn't plugged in but might be later so > I am just preparing the way) then > ln -s /cygdrive/h /h > works as before: the symlink /h exists, and is not called /h.exe. Hmm, I thought that a possible workaround might be using "ln -s /cygdrive/h. /h", even when h exists. It correctly created /h, supressing the .exe extension, but now "stat /h" shows that the link has length 12 but only points to the 11 characters /cygdrive/h (in other words, cygwin chopped the trailing dot from the link name, so it is reporting the wrong length). Furthermore, since /cygdrive/h. doesn't exist, the link is useless without any indication that it is broken because of the invisible trailing dot: $ ln -s /cygdrive/d. d $ readlink d /cygdrive/d $ stat d File: `d' -> `/cygdrive/d' Size: 12 Blocks: 1 IO Block: 1024 symbolic link Device: d47c93feh/3564934142d Inode: 50665495808013319 Links: 1 Access: (0777/lrwxrwxrwx) Uid: ( 1007/ eblake) Gid: ( 513/ None) Access: 2005-07-08 21:56:04.209000000 -0600 Modify: 2005-07-08 21:56:01.599625000 -0600 Change: 2005-07-08 21:56:01.599625000 -0600 $ ls d d@ $ ls d/ ls: d/: No such file or directory - -- Life is short - so eat dessert first!
