Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations.

Chfn

The chfn instruction can change the information seen through the finger instruction. This information is stored in the / etc/passwd file and displayed by the Finger program. The LinuxFinger command displays four pieces of information that can be changed by chfn: your real name, your workspace and phone, and your home phone. Any of these four messages can be specified on the command line. If no information is provided on the command line, chfn enters interactive mode. In interactive mode, chfn prompts for each field. At the prompt, you can enter new information or press back to leave the field unchanged. Enter the keyword "None" to make the field blank.

The scope of this command: RedHat, RHEL, Ubuntu, CentOS, SUSE, openSUSE, Fedora.
