The "ac" command stands for "accounting," and it is used to display accounting statistics for login/logout times of users on a Unix-like system.
The option "--individual-totals" is a flag that specifies that the output should include individual totals for each user's usage. When this flag is used, the "ac" command will provide a summary of each user's login and logout times, along with the total amount of time they have spent logged in. This can be useful for tracking the activity and usage patterns of individual users on the system.
By running the command "ac --individual-totals," you will get a list of users with their respective total login and logout times, allowing you to see how much time each user has spent actively using the system.
