Recursive chmod -> rw for files, rwx for directories

If you need to set change the attributes of all files and directories so that everyone can read (/ browse) them:

find /my/path \( -type d -exec chmod 755 {} \; \) -o \( -type f -exec chmod 644 {} \; \)

This will set the following rights for directories to user = rwx (read, write, execute), group = rx, others = rx and files to user = rw, group = r, others = r.
