RE: A good way to test if cygwin isn't installed?
On 3 Oct, Igor Pechtchanski wrote: Having mount.exe and cygwin1.dll in a specific dir and then run mount -m after set PATH=. should be the way to go. Yes, that was the idea. Igor Well, I was running this script from a version of Cygwin installed on the network. In other words, I want to avoid writing DOS batch scripts (since they really are such a sad waste of time). Bill Hughes's post of jscript + Windows scripting host looked interesting, but I didn't see a clear advantage to using that than to using Cygwin from the network: especially since the scripting host is only available on newer Windows OS versions - so it's not portable. And thanks to those who seemed to say that using mount is a good way to test. I was interested to see that seeing mount points only of the form /$CYGDRIVE_MNT/$DRIVE_LETTER/path-to-somewhere is a good indicator that Cygwin is not installed. Where CYGDRIVE_MNT can be determined this way: # Set CYGDRIVE_MNT to the mount point to be inserted in front of absolute # path names used to refer to drive mappings. By default the mount point # is /cygdrive, but if the user has set it to be / then $CYGDRIVE_MNT will # be empty. Basically, the user can choose /mnt or anything they like. # CYGDRIVE_MNT=`mount -p | sed -n '2s| .*||;s|^/$||;2p'` Overall though, all that seems more complicated than just using cygpath -w /, (cygpath / surely must use the mount info?), so I trust this is equivalent - and simpler for a script! As I mentioned, when I performed the experiment on a PC with Cygwin not installed, the output from cygpath -w / consisted of just a single backslash, which is an easy thing to check. luke -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

Yes, and furthermore, you have to have a running process that uses the cygwin1.dll on the machine. E.g., if you have Cygwin installed but no Cygwin processes running, mount will just work, even if there are two or more versions of cygwin1.dll on the machine (depending on the PATH, of course). Having mount.exe and cygwin1.dll in a specific dir and then run mount -m after set PATH=. should be the way to go. Yes, that was the idea.

end
when run it should give the foder mounted as '/'. It also won't work on a
9X/ME box as I don't know the registry key for that without digging.
When I get home I may have time to hack this together as a standalone, if
anyone is interested.
