\fBchfn\fR [\fI选项\fR] [\fI登录\fR]
.SH "描述"
.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 "选项"
.PP
The options which apply to the
\fBchfn\fR
command are:
.PP
\fB\-f\fR, \fB\-\-full\-name\fR\ \&\fIFULL_NAME\fR
.RS 4
更改用户的全名
.RE
.PP
\fB\-h\fR, \fB\-\-home\-phone\fR\ \&\fIHOME_PHONE\fR
.RS 4
Change the user\*(Aqs home phone number\&.
.RE
.PP
\fB\-o\fR, \fB\-\-other\fR\ \&\fIOTHER\fR
.RS 4
Change the user\*(Aqs other GECOS information\&. This field is used to store accounting information used by other applications, and can be changed only by a superuser\&.
.RE
.PP
\fB\-r\fR, \fB\-\-room\fR\ \&\fIROOM_NUMBER\fR
.RS 4
Change the user\*(Aqs room number\&.
.RE
.PP
\fB\-R\fR, \fB\-\-root\fR\ \&\fICHROOT_DIR\fR
.RS 4
Apply changes in the
\fICHROOT_DIR\fR
directory and use the configuration files from the
\fICHROOT_DIR\fR
directory\&. Only absolute paths are supported\&.
.RE
.PP
\fB\-u\fR, \fB\-\-help\fR
.RS 4
显示帮助信息并退出。
.RE
.PP
\fB\-w\fR, \fB\-\-work\-phone\fR\ \&\fIWORK_PHONE\fR
.RS 4
Change the user\*(Aqs office phone number\&.
.RE
.PP
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\&.
.SH "配置文件"
.PP
The following configuration variables in
/etc/login\&.defs
