Hi Corinna,
Perhaps not relevant anymore (since you have returned to the drawing board) ...
- after installing update 3 to Cygwin 2.0 ...
- created file while being logged on as user Test; subsequently executed:
chmod 460 file
- switched back to user Henri and attempted to touch file: failed
- however, using Cygwin 1.7, and repeating the same procedure, I am able to
touch the file (called file2)
Regards,
Henri
