## Find
### Change filtered permissions
Using find with its `exec` switch one can set different permissions based on the usual find filters.
One example would be only changing file or directory permissions.
`$ find (directory) -type f -exec chmod 744 {} +`
Replacing `-type f` with `-type d` would execute the `chmod` for directories instead.
