SYNOPSIS

chage [flaggor] [INLOGGNINGSNAMN]

BESKRIVNING

The chage 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 his/her password.

FLAGGOR

Flaggorna som gäller för kommandot chage är:

-d, --lastdaySISTA_DAG
    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).

-E, --expiredateUTGÅNGSDATUM
    Set the date or number of days since January 1, 1970 on which the user's 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 -1 as the EXPIRE_DATE will remove an account expiration date.

-h, --help
    Visa hjälpmeddelande och avsluta.

-I, --inactiveINAKTIV
    Set the number of days of inactivity after a password has expired before the account is locked. The INACTIVE 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.

    Passing the number -1 as the INACTIVE will remove an account's inactivity.

-l, --list
    Visa kontots åldringsinformation

-m, --mindaysMIN_DAGAR
    Sätter minimalt antal dagar mellan lösenordsändringar till MIN_DAGAR. Ett nollvärde för detta fält betyder att användaren kan ändra sitt lösenord när som helst.

-M, --maxdaysMAX_DAGAR
    Set the maximum number of days during which a password is valid. When MAX_DAYS plus LAST_DAY is less than the current day, the user will be required to change his/her password before being able to use his/her account. This occurrence can be planned for in advance by use of the -W option, which provides the user with advance warning.

    Passing the number -1 as MAX_DAYS will remove checking a password's validity.

-W, --warndaysVARN_DAGAR
    Set the number of days of warning before a password change is required. The WARN_DAYS option is the number of days prior to the password expiring that a user will be warned his/her password is about to expire.

If none of the options are selected, chage 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 [ ] marks.

NOTERA

Programmet chage kräver att en skugglösenordsfil finns tillgänglig.

The chage command is restricted to the root user, except for the -l option, which may be used by an unprivileged user to determine when his/her password or account is due to expire.
