+.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)\&. If the
+\fILAST_DAY\fR
+is set to
+\fI0\fR
+the user is forced to change his password on the next log on\&.
+.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\&.
+.sp
+For example the following can be used to set an account to expire in 180 days:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+ chage \-E $(date \-d +180days +%Y\-%m\-%d)
+
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Passing the number
+\fI\-1\fR
+as the
+\fIEXPIRE_DATE\fR
+will remove an account expiration date\&.
+.RE
+.PP
+\fB\-h\fR, \fB\-\-help\fR
+.RS 4
+显示帮助信息并退出。
+.RE
+.PP
+\fB\-i\fR, \fB\-\-iso8601\fR
+.RS 4
+When printing dates, use YYYY\-MM\-DD format\&.
+.RE
+.PP
+\fB\-I\fR, \fB\-\-inactive\fR\ \&\fIINACTIVE\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\-l\fR, \fB\-\-list\fR
+.RS 4
+显示账户年龄信息。
+.RE
+.PP
+\fB\-m\fR, \fB\-\-mindays\fR\ \&\fIMIN_DAYS\fR
+.RS 4
+Set the minimum number of days between password changes to
+\fIMIN_DAYS\fR\&. A value of zero for this field indicates that the user may change their password at any time\&.
+.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
+directory and use the configuration files from the
+\fICHROOT_DIR\fR
+directory\&. Only absolute paths are supported\&.
+.RE
+.PP
+\fB\-W\fR, \fB\-\-warndays\fR\ \&\fIWARN_DAYS\fR
+.RS 4
+Set the number of days of warning before a password change is required\&. The
+\fIWARN_DAYS\fR
+option is the number of days prior to the password expiring that a user will be warned their password is about to expire\&.
+.RE
+.PP
+If none of the options are selected,
+\fBchage\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
+\fI[ ]\fR
+marks\&.
+.SH "注意"
+.PP
+The
+\fBchage\fR
+program requires a shadow password file to be available\&.
+.PP
+The chage program will report only the information from the shadow password file\&. This implies that configuration from other sources (e\&.g\&. LDAP or empty password hash field from the passwd file) that affect the user\*(Aqs login will not be shown in the chage output\&.
+.PP
+The
+\fBchage\fR
+program will also not report any inconsistency between the shadow and passwd files (e\&.g\&. missing x in the passwd file)\&. The
+\fBpwck\fR
+can be used to check for this kind of inconsistencies\&.
+.PP
+The
+\fBchage\fR
+command is restricted to the root user, except for the
+\fB\-l\fR
+option, which may be used by an unprivileged user to determine when their password or account is due to expire\&.
+.SH "配置文件"
