Notice

• Pay attention to distinguishing the two commands whoami and logname; for example, we opened the terminal as user root and then switched to user user2. At this time, whoami returns the current user user2, and logname returns root. You can verify it by yourself.

• This command is a command in the GNU coreutils package. For related help information, please see man -s 1 logname, info coreutils 'logname invocation'.
