finger

Linux finger命令的功能是查询用户的信息,通常会显示系统中某个用户的用户名、主目录、停滞时间、登录时间、登录shell等信息。如果要查询远程机上的用户信息,需要在用户名后面接“@主机名”,采用[用户名@主机名]的格式,不过要查询的网络主机需要运行finger守护进程。

在我们的实验环境中,finger是需要安装的。

root@ubuntu:~# finger newer
The program 'finger' is currently not installed. You can install it by typing:
apt-get install finger

安装的命令是:

sudo apt-get install finger

直接输入finger ,查看当前登录用户

root@ubuntu:~# finger

newer     newer     *pts/0          Sep 24 08:47 (192.168.125.1)
