discover the directory that prevents a file from being read in linux

Question

i'm getting a permission denied for a user in a really long path.

$ sudo sudo -u user cat /l/o/n/g/path/file
Permission denied

i'm pretty sure path and file have permissions for that user. Is there any easy way to find which of the other directories in /l/o/n/g does not?

This will redirect the standard output of find to /dev/null, and display only the errors (including permission denied) while accessing directories.

find . -type d > /dev/null

nice! `find l/ -type d > /dev/null` `find: l/o/n: Permission denied` – gcb Oct 22 '13 at 00:18

If you're okay with limiting the check to user/group/other permissions, use

namei -l /l/o/n/g/path/file
