Is there way to rename user role name without plugin?

Is there anyway to rename a user role name via hook, instead of using plugin?

Edit

For example, administrator » owner

  1. function change_role_name() {
    global $wp_roles;

    if ( ! isset( $wp_roles ) )
        $wp_roles = new WP_Roles();

    //You can list all currently available roles like this...
    //$roles = $wp_roles->get_names();
    //print_r($roles);

    //You can replace "administrator" with any other role "editor", "author", "contributor" or "subscriber"...
    $wp_roles->roles['administrator']['name'] = 'Owner';
    $wp_roles->role_names['administrator'] = 'Owner';           
}
add_action('init', 'change_role_name');

  2. Actually, there are many ways to achieve that:

    With pure php and mysql you can edit the serialized entry in the db. Indeed, WordPress stores the serialized array of roles in wp_options table.

    So:

    1. Fetch the serialized array:
      SELECT option_value as serialized_string FROM wp_options WHERE option_name = 'wp_user_roles';
    2. Unserialize the string – php: $rolesArray = unserialize($serialized_string)
    3. Change the role name – php: $rolesArray['role_key']['name'] = "New name"
    4. Serialize back the array – php: echo serialize($rolesArray)
    5. Replace the db option_value content with output from the previous point

    If you feel confident with WordPress, you can even use the embedded WordPress REPL in wp-cli to fetch the stored value with get_option('wp_user_roles') and then use update_option to update it.

    And (always) remember to backup the db before options manipulation 😉

    Otherwise, if you don’t care about role_key value…

    …it’s very easy to achieve that with wp-cli:

    1. duplicate the existing role – $ wp role create new_role 'New Role' --clone=old_role
    2. delete the old one – $ wp role delete old_role
    3. then associate new_role to the user(s).
    4. eventually repeat step 1 and 2 until old_role = new_role

  3. If you are using WP version 4.7+ you may accomplish this using the wp_roles_init action like so:

    add_action( 'wp_roles_init', static function ( WP_Roles $roles ) {
    $roles->roles['administrator']['name'] = 'Owner';
    $roles->role_names['administrator'] = 'Owner';
} );

  6. You can edit it directly in your DB, and it will be edited permanently for your website. Here is where WP keeps user roles

    SELECT * from blog_options WHERE option_name = 'blog_user_roles'
