.SH "NAME"

.SH "\(:UBERSICHT"
.HP \w'\fBchfn\fR\ 'u
\fBchfn\fR [\fIOptionen\fR] [\fIANMELDENAME\fR]
.SH "BESCHREIBUNG"
.PP
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\&.
.SH "OPTIONEN"
.PP
The options which apply to the
\fBchfn\fR
command are:
.PP
\fB\-f\fR, \fB\-\-full\-name\fR\ \&\fIFULL_NAME\fR

directory\&. Only absolute paths are supported\&.

If none of the options are selected,
\fBchfn\fR
operates in an interactive fashion, prompting the user with the current values for all of the fields\&. Enter the new value to change the field, or leave the line blank to use the current value\&. The current value is displayed between a pair of
\fB[ ]\fR
marks\&. Without options,
\fBchfn\fR
prompts for the current user account\&.
