last: View all logins by a specific user and show the IP address instead of the hostname.
$ last ${username} -i
try on your machine
The command "last ${username} -i" is used to display the login history of a specific user, indicated by ${username}.
Here is a breakdown of the command:
- "last" is a command in Unix-like operating systems that retrieves information about previous logins.
- "${username}" is a placeholder for the actual username of the user whose login history you want to view. Replace this with the desired username.
- "-i" is an option or flag that specifies that the command should display the IP addresses associated with the login history.
Putting it all together, when you execute the "last ${username} -i" command, it will print a list of the user's previous logins, along with the date, time, and IP address from which each login originated.
