lchage [OPTION]... user
Displays or allows changing password policy of user.
- -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.
The exit status is 0 on success, nonzero on error.
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.
