Script or utility to list all files on the system that a certain user can read/modify

[Feathers McGraw]

Does anyone know of a utility or script that can scan a whole filesystem and list files that are writable by a certain user? Same for all files readable by a certain user.

I feel like this would be a useful tool for doing quick security tests to make sure no file permissions have been set too loose.

with findutils 4.3+ you can use:

find [path] [-readable|-writable]

for example, "find / -readable".

to search for another (not active) user:
sudo -u [userrname] find / -writable
