How to check account expiration?

To check the account expiration date for a user in Linux, you can use the chage command. Here’s how to do it:

Open a terminal.
Run the following command, replacing username with the actual username you want to check:
```
sudo chage -l username
```

This command will display detailed information about the user's account, including:

Last password change
Password expiration
Password inactive
Account expiration

The output will include a line that specifies the "Account expires" date, which indicates when the account will be disabled if an expiration date has been set. If it shows "never," it means the account does not have an expiration date.
