ac: Print how long a particular user has been connected in hours.

$ ac --individual-totals ${username}

try on your machine

This command is using the "ac" command in a Unix-like operating system (such as Linux) to display individual totals of logged-in time for a specific user.

Here's a breakdown of the command:

"ac": It is the command used to display statistics about users' connect time. It counts the amount of time a user is logged in and the number of connect sessions made by each user.
"--individual-totals": It is an option or flag used with the "ac" command. This option tells the command to provide individual totals for each user, rather than a combined total.
"${username}": It is a placeholder or variable that should be replaced with the actual username, for whom the individual total logged-in time is to be checked. For example, if the username is "john", you should replace ${username} with 'john' in the command.

So, by running this command with the appropriate username, it will display the total time the specified user has spent logged in.
