On a Linux (ubuntu) machine, an automated script running as a normal user is creating a subdirectory under its home directory. For some reason, the directory is created with
Access: (0000/d---------). umask is 0022. This obviously means the script can't create any files in that directory.
Can anyone think of anything?
Apparently this only happens with the non-superuser account.
Update: The problem was actually a bug. mkdir was called as a system command from C code, not as the command-line utility. And the programmer who called it used mode=0...
Anyway - the reason it DID work when running as root, is that root can create files in directories even when the permissions don't allow it.
