j@uriah 155% ac
total 1001.49
The normal tools to examine the utmp file are who(1), and w(1). The
regular tool to examine wtmp is last(1).
ac(8) is a fairly complex accounting command, and you need to RTFM
well in order to use it the way you actually intend. The default
display is a little silly:
If no arguments are given, ac displays the total connect time for all ac-
counts with login sessions recorded in wtmp.
