Question

Hi guys I need to find the deepest nested writable folder:

I write this command: find . -type d -printf '%d:%p\n' | sort -n | tail -1

But how to add the condition “Is this folder writable”?

Answer 1

Try doing this :

find . -type d -writable -printf '%d:%p\n' | sort -n | tail -1

man find said :

-writable

Matches files which are writable. This takes into account access control lists and other permissions artefacts which the
-perm test ignores. This test makes use of the access(2)
system call, and so can be fooled by NFS servers which do UID mapping (or root-squashing), since many systems implement
access(2) in the client’s kernel and so cannot make use of the
UID mapping information held on the server.

This works for dirs too.
