Change the ownership of all files & folders based on search result

Question

I know how to find all the files & folders owned by a specific user, say tommy:

find / -user tommy

But how can I chown the files & folders to another user, say peter?

I know I can change specific files & folder via this command:

sudo chown -R peter /the/specific/folder

Answer 1

You can use something like this:

find / -user tommy -exec chown peter {} \;
