Chfn

Linux chfn command

On Unix-like operating systems such as Linux, chfn modifies a user's "finger" information. This information is stored in the file /etc/passwd, and includes the user's real name, work room, work phone number, and home phone number.

This information can be viewed by other users with the finger command.

Syntax

chfn -f full_name -r room_no -w work_ph -h home_ph -o other user
-f full_name

Allows someone to change their full name on their account.

-r room_no

Allows someone to change their room number on their account.

-w work_ph

Allows someone to change their work phone number on their account.

-h home_ph

Allows someone to change their home phone number on their account.

-o other

Allows someone to change any other notes on their account.

user

The name of the user who is being changed.

Examples
chfn
Running the command without any options will enable the user to change all the user information.

Note

If you're attempting to change the actual username and not just the description of the user, you may want to edit the password file directly; see the vipw command for more information.
