|
|
The
|
|
\fBchfn\fR
|
|
command changes user fullname, office room number, office phone number, and home phone number information for a user\*(Aqs account\&. This information is typically printed by
|
|
\fBfinger\fR(1)
|
|
and similar programs\&. A normal user may only change the fields for her own account, subject to the restrictions in
|
|
/etc/login\&.defs\&. (The default configuration is to prevent users from changing their fullname\&.) The superuser may change any field for any account\&. Additionally, only the superuser may use the
|
|
\fB\-o\fR
|
|
option to change the undefined portions of the GECOS field\&.
|
|
.PP
|
|
These fields must not contain any colons\&. Except for the
|
|
\fIother\fR
|
|
field, they should not contain any comma or equal sign\&. It is also recommended to avoid non\-US\-ASCII characters, but this is only enforced for the phone numbers\&. The
|
|
\fIother\fR
|
|
field is used to store accounting information used by other applications\&.
