This information is used by the system to determine when a user must change their password\&. .SH "OPCJE" .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 Ustawia datę, począwszy od kt\('orej konto użytkownika nie będzie już dostępne\&. \fIDATA_WAŻN\fR jest liczbą dni od 1 stycznia 1970, od kt\('orej konto jest blokowane\&. Data może być też wyrażona w formacie RRRR\-MM\-DD (lub innej, powszechniej używanej w danym regionie)\&. Użytkownik, kt\('orego konto jest zablokowane musi skontaktować się z administratorem systemu zanim będzie m\('og\(/l z niego ponownie skorzystać\&. .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 Wyświetlenie komunikatu pomocy i zakończenie dzia\(/lania\&. .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 Wyświetlenie informacji o terminach ważności konta i has\(/la\&. .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\-P\fR, \fB\-\-prefix\fR\ \&\fIPREFIX_DIR\fR .RS 4 Apply changes to configuration files under the root filesystem found under the directory \fIPREFIX_DIR\fR\&. This option does not chroot and is intended for preparing a cross\-compilation target\&. Some limitations: NIS and LDAP users/groups are not verified\&. PAM authentication is using the host files\&. No SELINUX support\&. .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 "UWAGI" .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 The following configuration variables in /etc/login\&.defs change the behavior of this tool: .SH "PLIKI" .PP /etc/passwd .RS 4 Informacja o kontach użytkownik\('ow\&. .RE .PP /etc/shadow .RS 4 Informacje chronione o użytkownikach\&. .RE .SH "KOD ZAKOŃCZENIA" .PP The \fBchage\fR command exits with the following values: .PP \fI0\fR .RS 4 success .RE .PP \fI1\fR .RS 4 permission denied .RE .PP \fI2\fR .RS 4 invalid command syntax .RE .PP \fI15\fR .RS 4 can\*(Aqt find the shadow password file .RE .SH "ZOBACZ TAKŻE" .PP \fBpasswd\fR(5), \fBshadow\fR(5)\&.
