NAMElchage − Display or change user password policy
SYNOPSISlchage [OPTION]... user
DESCRIPTIONDisplays 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 password. −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 STATUSThe exit status is 0 on success, nonzero on error.
NOTESNote 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. 0
