Finding Files

4.5 Fixing Permissions

Suppose you want to make sure that everyone can write to the directories in a certain directory tree. Here is a way to find directories lacking either user or group write permission (or both), and fix their permissions:

find . -type d -not -perm -ug=w | xargs chmod ug+w
