Change information about user password expirations. If run without any option flags, chage will prompt for values to be entered; you may also use option flags to change or view information.
Options

Maximum number of days between password changes.

- -I inactive-days
If a password expires and the user does not log in for this number of days, the account will be locked, and the user must contact a system administrator before logging in. Set to 0 to disable the feature.
- -E expiredate
Set the date when the account will be locked. This is not a date for password expiration, but for account expiration. It may be expressed as a YYYY-MM-DD date or as a number of days since January 1, 1970.

The number of days before password expiration that a user will be warned to change passwords.
