ping returns success on failure
Ping returns zero (0) after a successful response from a remote host. It returns one (1) if it's called with a unknown domain name -- a failure.

Re: How can I copy the configuration from one PC to another?
Hi! I think that several people have this problem: If you get a new PC you have to manually switch on all programs that you want or need. Is it possible to copy the configuration from one PC to another and if, how? This isn't necessarily a Cygwin question. But it's a very important question with only one reasonable answer, in my opinion. If you want to move all software from one computer to another then check out Acronis True Image with the Universal Restore option. It will restore a Ghost-like backup to just about any other PC, automatically handling the change of devices. I have nothing to do with Acronis other than being a satified customer.

We're automating administration of large numbers (hundreds) of workstations. Windows can't handle most of this stuff. But with Cygwin we're finding ways. It's cheap, fast, powerful, flexible, extensible. The mentality that keeps coming back to the limited set of Windows tools for administration is a very constricting and costly one. Thanks for the uninstall lead. That's the key. Looking good. Regtool can accomplish the same things as expensive 3rd-party Windows tools, with a lot less grief. (And without the straightjacket.) Not expecting this to become a mainstream part of this list, just asking for leads and experiences of others. Cygwin is the key. (My query was not for an uninstall.

If you've set up sshd on the remote machine, 'ssh MACHINE cygcheck -cd' ought to do it. Otherwise, looking at the drive is probably not going to get you anything reliably (in a way that's guaranteed to always work). For a non-portable hack using the current settings, look at the source of the Cygwin setup program. Incidentally, most software leaves traces in the registry, at well-known keys, so the easiest way to check for it is look in the registry (as it may actually be installed anywhere). The same is the case with Cygwin (look for HK(LM|CU)/Software/Cygnus Solutions/Cygwin -- even though the mount information might be moved out at some point, the key itself will probably stay around). Though how you intend to browse the registry on a mounted drive is not very clear. HTH, Igor -- Thanks very much for the response. This is a large network of clients.

Re: mount never fails ... sorta
Richard Foulk wrote: Give mount(1) nonexistent hosts or directories and it will complain, but it still populates the mount table as if it succeeded. It also always returns zero, for success or failure. Cygwin's mount is a different bird than on Unix. It really is just a mapping table of POSIX names to DOS or UNC-style paths. It is not required that the POSIX path exist for things to work. But since most people coming from a UNIX background expect that it does and it certainly helps things like shell path completion if the paths do already exist, you get a warning to let you know about this difference. I guess I should have said mount's behavior is wrong and broken. It knows when there's an error it just does the wrong things. 1. mount reports the error to stderr, but not via the return code. 2. mount knows about the error but signals success anyway -- by listing a (non-existent) mount within the mount table. Sure Cygwin's mount is different than Unix's. That's what Cygwin is all about, hiding those differences. Cygwin's mount fails at that. Registering a mount that doesn't exist is quite broken.

mv does copy instead of rename
In an Active Directory environment Windows Explorer was refusing to rename a directory, presumably because the directory was open by another process. On trying mv under Cygwin to rename the directory, mv seemed to just hang. It was a large directory and mv was actually copying the files to the new named directory (on the same partition.) Does this seem like appropriate behaviour? It was certainly unexpected. I'm pretty sure mv is never supposed to do this on Unix.
