Afterword
The first execution works because it only changes the user owner to root, but the second execution fails because it changes the user and group owner to root, and the others only have read permissions. Executing sudo chown root: ~ changes the user and group all at once, while sudo chown :root changes only the group. sudo chown $(who | awk ‘{print $1}’): start_chown_changeGroupOwner.sh obtains the account name from the $(who | awk ‘{print $1}’): part and changes the user and group of the files all at once.
