'*' is a valid filename character (if not, please cite the part of POSIX that claims that). AFAIK, the only invalid filename character is '/', which is a directory separator. The problem with /proc/registry is that '/' is a valid value name character, so keys like "HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2\/usr/bin" end up as "/proc/registry/HKEY_LOCAL_MACHINE/SOFTWARE/Cygnus\ Solutions/Cygwin/mounts\ v2'/usr/bin'", which any Cygwin program (including bash) will choke on. > If the findutils maintainer decides to add a /proc/registry patch to > make '*' a valid filename char, other fileutils should be fixed also. > ls and cat at least. > > So it should be better "fixed" in cygwin.

Which? If there's a solution, it should probably have something in common with managed mounts...
