-E, --expiredate EXPIRE_DATE

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.


 -I, --inactive INACTIVE

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
Show account aging information.

    

 -m, --mindays MIN_DAYS

Set the minimum number of days between password changes to MIN_DAYS. A value of zero for this field indicates that the user may change his/her password at any time.

    

 -M, --maxdays MAX_DAYS
          

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.
