lchage - Display or change user password policy SYNOPSIS lchage [OPTION]... user DESCRIPTION Displays or allows changing password policy of user. OPTIONS
-d, date=days Set the date of last password change to days after Jan 1 1970.
Set days to -1 to disable password expiration (i.e. to ignore mindays, and maxdays and related settings). Set days to 0 to enforce password change on next login. (This also disables password expiration until the password is changed.)
-E, expire=days Set the account expiration date to days after Jan 1 1970. Set
days to -1 to disable account expiration.
-i, interactive Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration.
-I, inactive=days Disable the account after days after password expires (after the
user is required to change the password). Set days to -1 to keep the account enabled indefinitely after password expiration.
-l, list Only list current user's policy and make no changes.
-m, mindays=days Require at least days days between password changes. Set days
to 0 or -1 to disable this requirement. If this value is larger than the value set by maxdays, the user cannot change the pasword.
-M, maxdays=days Require changing the password after days since last password
change. Set days to -1 to disable password expiration.
-W, warndays=days Start warning the user days before password expires (before the
user is required to change the password). Set days to 0 or -1 to disable the warning. EXIT STATUS The exit status is 0 on success, nonzero on error. NOTES Note that “account expiration” (set by expire) is distinct from “password expiration” (set by maxdays). Account expiration happens on a fixed date regardless of password changes. Password expiration is relative to the date of last password change. libuser Nov 8 2012 lchage(1)
