There's your problem - you are expecting sane quoting rules from cmd. The quoting rules for cmd are vastly different from the quoting rules for bash itself. Also, remember that cmd does not do globbing before invoking a command, but neither do cygwin apps do it on entry (they expect the shell to have already done it). Therefore, when a cygwin app detects that it was invoked by a non-cygwin app, cygwin must do the globbing before main(); and yes, the rules for what cygwin1.dll will try to glob depend heavily on how much the command line argument passed by cmd looks like it might need globbing. You may be better off writing a shell script with the command you really want to run, and just calling 'bash path/to/script' than trying to call 'bash -c "complicated command"' from cmd. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
