chage -l means "list account expiration information." The -l switch does not change anything; it merely displays information.
When I do chage -l [my user name] on this computer, I get
Last password change : [date]
Password expires : never
Password inactive : never
Account expires : never
Minimum number of days between password change : 0
Maximum number of days between password change : 99999
Number of days of warning before password expires : 7
User can use chage -l to see how long his account is valid. Only root can use the other chage switches.
