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, --lastday SISTA_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, --expiredate UTGÅNGSDATUM
           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, --inactive INAKTIV
           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, --mindays MIN_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, --maxdays MAX_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.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the
           CHROOT_DIR directory.

       -W, --warndays VARN_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.

       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
