+.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"

+The following configuration variables in

+The

+\fIlogin:\fR
+prompt on the user\*(Aqs terminal\&.
+\fBlogin\fR
+may be special to the shell and may not be invoked as a sub\-process\&. When called from a shell,
+\fBlogin\fR
+should be executed as
+\fBexec login\fR
+which will cause the user to exit from the current shell (and thus will prevent the new logged in user to return to the session of the caller)\&. Attempting to execute
+\fBlogin\fR
+from any shell but the login shell will produce an error message\&.
+.PP
+The user is then prompted for a password, where appropriate\&. Echoing is disabled to prevent revealing the password\&. Only a small number of password failures are permitted before
+\fBlogin\fR
+exits and the communications link is severed\&.
+.PP
+If password aging has been enabled for your account, you may be prompted for a new password before proceeding\&. You will be forced to provide your old password and the new password before continuing\&. Please refer to
+\fBpasswd\fR(1)
+for more information\&.
+.PP
+After a successful login, you will be informed of any system messages and the presence of mail\&. You may turn off the printing of the system message file,
+/etc/motd, by creating a zero\-length file
+\&.hushlogin
+in your login directory\&. The mail message will be one of "\fIYou have new mail\&.\fR", "\fIYou have mail\&.\fR", or "\fINo Mail\&.\fR" according to the condition of your mailbox\&.
+.PP
+Your user and group ID will be set according to their values in the

+file\&. The value for
+\fB$HOME\fR,
+\fB$SHELL\fR,
+\fB$PATH\fR,
+\fB$LOGNAME\fR, and
+\fB$MAIL\fR
+are set according to the appropriate fields in the password entry\&. Ulimit, umask and nice values may also be set according to entries in the GECOS field\&.
+.PP
+On some installations, the environmental variable
+\fB$TERM\fR
+will be initialized to the terminal type on your tty line, as specified in

+The

+file specifies (user, host) combinations and/or (user, tty) combinations for which a login will be either accepted or refused\&.
+.PP
+When someone logs in, the
+\fIlogin\&.access\fR
+is scanned for the first entry that matches the (user, host) combination, or, in case of non\-networked logins, the first entry that matches the (user, tty) combination\&. The permissions field of that table entry determines whether the login will be accepted or refused\&.
+.PP
+登录访问控制表的每一行有\(lq:\(rq分隔的三个字段：

+\fIpermission\fR:\fIusers\fR:\fIorigins\fR
+.PP
+The first field should be a "\fI+\fR" (access granted) or "\fI\-\fR" (access denied) character\&. The second field should be a list of one or more login names, group names, or

+.PP
+The
+/etc/login\&.defs
+file defines the site\-specific configuration for the shadow password suite\&. This file is required\&. Absence of this file will not prevent system operation, but will probably result in undesirable operation\&.
+.PP
+This file is a readable text file, each line of the file describing one configuration parameter\&. The lines consist of a configuration name and value, separated by whitespace\&. Blank lines and comment lines are ignored\&. Comments are introduced with a "#" pound sign and the pound sign must be the first non\-white character of the line\&.
+.PP
+Parameter values may be of four types: strings, booleans, numbers, and long numbers\&. A string is comprised of any printable characters\&. A boolean should be either the value
+\fIyes\fR
+or
+\fIno\fR\&. An undefined boolean parameter or one with a value other than these will be given a
+\fIno\fR
+value\&. Numbers (both regular and long) may be either decimal values, octal values (precede the value with
+\fI0\fR) or hexadecimal values (precede the value with
+\fI0x\fR)\&. The maximum value of the regular and long numeric parameters is machine\-dependent\&.
+.PP
+提供如下配置项：
+.PP
+\fBPASS_MAX_DAYS\fR,
+\fBPASS_MIN_DAYS\fR
+and
+\fBPASS_WARN_AGE\fR
+are only used at the time of account creation\&. Any changes to these settings won\*(Aqt affect existing accounts\&.
