Answer 1

Piping to xargs is a dirty way of doing that which can be done inside of find.

find . -type d -exec chmod 0755 {} \; find . -type f -exec chmod 0644 {} \; 

You can be even more controlling with other options, such as:

find . -type d -user harry -exec chown daisy {} \; 

You can do some very cool things with find and you can do some very dangerous things too. Have a look at "man find", it's long but is worth a quick read. And, as always remember:

• If you are root it will succeed.
• If you are in root (/) you are going to have a bad day.
• Using /path/to/directory can make things a lot safer as you are clearly defining where you want find to run.

Answer 2

A good alternative is this:

find . -type f | xargs chmod -v 644 

and for directories:

find . -type d | xargs chmod -v 755 

and to be more explicit:

find . -type f | xargs -I{} chmod -v 644 {}
