.SH "SYNOPSIS"
.HP \w'\fBchage\fR\ 'u
\fBchage\fR [\fIflaggor\fR] \fIINLOGGNINGSNAMN\fR
.SH "BESKRIVNING"
.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 "FLAGGOR"
.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
Visa hj\(:alpmeddelande och avsluta\&.
.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
Visa kontots \(oaldringsinformation
.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 "NOTERA"
.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 "CONFIGURATION"
.PP

/etc/login\&.defs
