Linux chage command - change user password expiry information.

To view current password expiry date info for a user, use the -l command-line option.

chage -l [USERNAME]

$ chage -l ec2-user

       If none of the options are selected, chage operates in an interactive
       fashion, prompting the user with the current values for all of the
       fields. Enter the new value to change the field, or leave the line
       blank to use the current value. The current value is displayed between
       a pair of [ ] marks.
