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.
