Checking/modifying file permissions on an underlying directory


If you have a file system (nfs, etc.) mounted on-top of a directory and you need to see file permissions, ACLs, etc. of the underlying directory and not the mounted fs then:

Solaris:

# mount -F lofs -o nosub /some/path/ /mnt/fix

Linux:

# mount -B /some/path/ /mnt/fix

If you access /mnt/fix now you won't see any mounted filesystems on top of any directories, just the underlying fs.


I used it in the past and forgot about it, needed it yesterday and found it here.
