Joe。IT 部門のユーザーは、Linux サーバー上の機密ファイルへの変更を保存できません。次のリストは、次のとおりです。サーバー技術者が、他のユーザーに過度のアクセス権を与えることなく Joe にアクセスを許可できる最適なコマンドはどれですか。
正解:C
The chmod command is used to change the permissions of files and directories. The g+w option means to grant write permission to the group owner of the file. Since Joe is a member of the IT group, which is also the group owner of the file, this command will allow him to save changes to the file without affecting the permissions of other users.
