Fix file permissions in Mac OS X
A few days ago I copied a bunch of files/folders from an external NTFS formatted hard drive to my MacBook. The files where copied ok, but the permissions where messed up. How did I fix them? With this simple command: $ chmod -Rv u=rwx,g=rx,o=r username path_to_base_folder It recursively goes through all files and folders and fix their permissions. Source!
