Yes you can all this by chage command but there is another easy method to get this information
and this is by using /etc/shadow file. This is the file which contains all the details related to the user passwords. Lets see how shadow file gives details.
File:/etc/shadow
A. /etc/shadow file stores actual password in encrypted format for user's account with additional properties related to user password i.e. it stores secure user account information. All fields are separated by a colon (
symbol. It contains one entry per line for each user listed in /etc/passwd file Generally, shadow file entry looks as follows
FIELDS : FUNCTION
----------------------------------------------------------------
1. User name : It is your login name
2. Password: It your encrypted password. The password should be minimum 6-8 characters long including special characters/digits
3. Last password change (lastchanged): Days since Jan 1, 1970 that password was last changed
4. Minimum: The minimum number of days required between password changes i.e. the number of days left before the user is allowed to change his/her password
5. Maximum: The maximum number of days the password is valid (after that user is forced to change his/her password)
6. Warn : The number of days before password is to expire that user is warned that his/her password must be changed
7. Inactive : The number of days after password expires that account is disabled
8. Expire : days since Jan 1, 1970 that account is disabled i.e. an absolute date specifying when the login may no longer be used
The last 6 fields provides password aging and account lockout features (you need to use chage command to setup password aging). According to man page of shadow - the password field must be filled.
Thanks a lot
