Do you have to be root to use chown?

chown is a privilege restricted to root, since otherwise you could pawn off your files on other users to avoid quota restrictions. More precisely, you can chown files that you own to change their group ownership information, but you can only change user ownership if you are root.

Does chown require Sudo?

You only have to run sudo if you change the owner or the group to a group you don’t belong to. You don’t need sudo to change the group to a group you already belong to.

Since you are the only user on the system, and therefore the only user of the scripts that you write, I don’t really see much point in installing personal scripts in /usr/local/bin. Installing scripts in /usr/local/bin would only make it more awkward to back up and to maintain your personal files.
