BESCHREIBUNG

The chage command changes the number of days between password changes and the date of the last password change. This information is used by the system to determine when a user must change their password.

ANMERKUNGEN

The chage program requires a shadow password file to be available.

The chage program will report only the information from the shadow password file. This implies that configuration from other sources (e.g. LDAP or empty password hash field from the passwd file) that affect the user's login will not be shown in the chage output.

The chage program will also not report any inconsistency between the shadow and passwd files (e.g. missing x in the passwd file). The pwck can be used to check for this kind of inconsistencies.

The chage command is restricted to the root user, except for the -l option, which may be used by an unprivileged user to determine when their password or account is due to expire.
