phone number information for a user's account. This information is

may only change the fields for their own account, the super user may
change the fields for any account. Also, only the super user may use
the -o option to change the undefined portions of the GCOS field.

a pair of [ ] marks. Without options, chfn prompts for the current
The file, /etc/login.defs, defines some configuration options that
affects how chfn operates, especially for non-root users.
/etc/passwd - user account information
/etc/login.defs - config options for chfn
