ac
The ac command line tool is often used to print out statistics about user logins, including the time when a user has logged in and out. The name "ac" is an abbreviation for "accounting."
Typically, the ac command is run with the -p option to retrieve the details from the system's accounting logs. These logs contain information about user sessions, such as duration, idle time, number of processes, and more.
The ac command output is usually organized by day, and it shows individual user statistics, as well as summary information. It can be helpful for system administrators to monitor user activity patterns, track resource usage, or identify potential security issues.
Please note that the availability and functionality of the ac command may vary depending on the operating system and its version.
