\fBchage\fR [\fI选项\fR] \fI登录\fR
.SH "描述"
.PP
The
\fBchage\fR
command changes the number of days between password changes and the date of the last password change\&. This information is used by the system to determine when a user must change their password\&.
.SH "选项"
.PP
The options which apply to the
\fBchage\fR
command are:
.PP
\fB\-d\fR, \fB\-\-lastday\fR\ \&\fILAST_DAY\fR
.RS 4
Set the number of days since January 1st, 1970 when the password was last changed\&. The date may also be expressed in the format YYYY\-MM\-DD (or the format more commonly used in your area)\&.
.RE
.PP
\fB\-E\fR, \fB\-\-expiredate\fR\ \&\fIEXPIRE_DATE\fR
.RS 4
Set the date or number of days since January 1, 1970 on which the user\*(Aqs account will no longer be accessible\&. The date may also be expressed in the format YYYY\-MM\-DD (or the format more commonly used in your area)\&. A user whose account is locked must contact the system administrator before being able to use the system again\&.

Passing the number
\fI\-1\fR
as the
\fIEXPIRE_DATE\fR
will remove an account expiration date\&.

.RE
.PP
\fB\-i\fR, \fB\-\-iso8601\fR

.RS 4
Set the number of days of inactivity after a password has expired before the account is locked\&. The
\fIINACTIVE\fR
option is the number of days of inactivity\&. A user whose account is locked must contact the system administrator before being able to use the system again\&.
.sp
Passing the number
\fI\-1\fR
as the
\fIINACTIVE\fR
will remove an account\*(Aqs inactivity\&.

.RE
.PP
\fB\-m\fR, \fB\-\-mindays\fR\ \&\fIMIN_DAYS\fR
.RS 4
Set the minimum number of days between password changes to

.RE
.PP
\fB\-M\fR, \fB\-\-maxdays\fR\ \&\fIMAX_DAYS\fR
.RS 4
Set the maximum number of days during which a password is valid\&. When
\fIMAX_DAYS\fR
plus
\fILAST_DAY\fR
is less than the current day, the user will be required to change their password before being able to use their account\&. This occurrence can be planned for in advance by use of the
\fB\-W\fR
option, which provides the user with advance warning\&.
.sp
Passing the number
\fI\-1\fR
as
\fIMAX_DAYS\fR
will remove checking a password\*(Aqs validity\&.
.RE
.PP
\fB\-R\fR, \fB\-\-root\fR\ \&\fICHROOT_DIR\fR
.RS 4
Apply changes in the
\fICHROOT_DIR\fR

\fI[ ]\fR
marks\&.

The
\fBchage\fR
program requires a shadow password file to be available\&.
