 ### Change filtered permissions

-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.

 ### Overwrite disk with pseudorandom data
+
 Using openssl on CPUs with AES acceleration one can create pseudorandom data with high speeds.  
-Much faster than `/dev/urandom` at least  
-`# openssl enc -aes-128-ctr -md sha512 -pbkdf2 -nosalt -pass file:/dev/urandom < /dev/zero | pv > (target disk)`  
-Around 2GiB/s on my Ryzen 7 1700x if output to `/dev/null`
