Linux Command大全

The Linux finger command allows users to query information about other users. The information listed includes:

• Login Name
• User Name
• Home directory
• Shell
• Login status
• Mail status
• .plan
• .project
• .forward

Among them, .plan, .project, and .forward are the information in the .plan, .project, and .forward files in the user's Home Directory. If there is none, there is none. The finger command is not limited to querying on the same server and can also search for a user on a remote server. As long as you give an address like E-Mail address: Any general address is fine.

Usage rights: All users.
