"cygpath -u" inside backticks differs
It may be something very simple, but I just cannot figure what it is, nor can I find anything on the forums. Here - see the different results: / > echo `cygpath.exe -u '\\DAEMON1\anrdaemon\.profile'` /c/DAEMON1/anrdaemon/.profile / > cygpath.exe -u '\\DAEMON1\anrdaemon\.profile' //DAEMON1/anrdaemon/.profile So cygpath in backticks slaps a drive at the front, while otherwise it does ... well, what I expect. Does anyone know why? Or know a thread where this is explained? Many thanks!

Eric - thanks for the info! I see the problem, yes, and it is simple - I have completely "slepth through" the $() business :-) I am all set now - thanks!

I've been using `` for years, and never heard of $(). What version did this change? I think I need to go back and re-read some documentation!

What version did this change? $() has existed in all sh variant shells except Solaris /bin/sh pretty much since the 80s; it was standardized in POSIX in the 90s. (On Solaris, you have to use /usr/xpg4/bin/sh instead of /bin/sh to get it) -- Eric Blake eblake redhat com+1-919-301-3266 Libvirt virtualization library http://libvirt.org signature.asc Description: OpenPGP digital signature
