Welcome
kumar7997,
I have a few to questions pose in response first:-
- Is this homework/assignment? There are specific forums for these.
- What have you tried so far?
- What output/errors do you get?
- What are your preferred tools? (C, shell, perl, awk, etc.)
- What logical process have you considered? (to help steer us to follow what you are trying to achieve)
Most importantly,
What have you tried so far?
Giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.
We're all here to learn and getting the relevant information will help us all. The password details are stored in
/etc/security/passwd with the password rules stored in
/etc/security/user. You will need to check the last update time against the current time with reference to the rules you have set in order to decide if the password is due to expire within any given period.
I hope that this helps, but if not, show us how far you have managed and explain what is not working, with all code, files input & output/errors wrapped in CODE tags.
Thanks,
Robin
