How to Use chown

 https://linuxize.com/post/linux-chown-command/

Before going into how to use the chown command, let’s start by reviewing the basic syntax.

The chown command expressions takes the following form:

chown [OPTIONS] USER[:GROUP] FILE(s)

USER is the user name or the user ID (UID) of the new owner. GROUP is the name of the new group or the group ID (GID). FILE(s) is the name of one or more files, directories or links. Numeric IDs should be prefixed with the + symbol.

• USER - If only the user is specified, the specified user will become the owner of the given files, the group ownership is not changed.
• USER: - When the username is followed by a colon :, and the group name is not given, the user will become the owner of the files, and the files group ownership is changed to user’s login group.
• USER:GROUP - If both the user and the group are specified (with no space betwen them), the user ownership of the files is changed to the given user and the group ownership is changed to the given group.
• :GROUP - If the User is omitted and the group is prefixed with a colon :, only the group ownership of the files is changed to the given group.
• : If only a colon : is given, without specifying the user and the group, no change is made.

By default, on success, chown doesn’t produce any output and returns zero.
