Detailed introduction to the use of Linux finger commands

Linux allows multiple users to log in at the same time using a different terminal, and theLinux Finger command provides the system administrator with a way to know how many users are using the Linux host at some point , and for this simple command, let's start by introducing an example.

The function of the Linux finger command is to query the user's information, which usually displays the user name, home directory, time of inactivity, logon time, login shell and other information of a user in the system. If you want to query the user information on the remote computer, you need to follow the user name "@ hostname", the [username @ hostname] format, but to query the network host needs to run the finger daemon.

The general format of the command is:

finger [options] [users] [user @ host]

The meanings of the options in the command are as follows:

-S displays information such as the user's registered name, actual name, terminal name, write status, stall time, logon time, and so on.

-L In addition to the information displayed with the-s option, it also displays information such as the user's home directory, login shell, message status, and the contents of the. Plan,. Project, and. Forward files in the user's home directory.

-P is the same as the-l option except that the. plan file and the. project file are not displayed.
