The command "last -n ${login_count}" is used to display a certain number of last logged-in users.

The "last" command is a tool in Unix-like systems (including Linux) that shows a list of previously logged-in users. It provides information such as the user's login name, the terminal from which they logged in, the date and time of their login, and the duration of their session.

The "-n" option is used to specify the number of last logged-in users to display. In this case, ${login_count} is a placeholder that is expected to be replaced with an actual numeric value. For example, if ${login_count} is set to 5, the command will display the last 5 logged-in users.

Overall, the command "last -n ${login_count}" helps in retrieving a list of recently logged-in users, which can be useful for system administrators or for monitoring user activities.
