ac: command not found

by admin

The ac command is a utility for displaying statistics about user activity on a Linux system. It reads data from the system’s accounting files and displays a summary of information about users’ login and logout times, the amount of time they spent logged in, and the number of processes they ran.

You can also use the -f option to specify the name of the accounting file to read data from. By default, ac reads data from the system’s default accounting file, which is usually located at /var/account/pacct.

For more information about the ac command and a complete list of options, you can refer to the man page by typing “man ac” at the command prompt.
