I do the following:
who -u /var/log/wtmp > /var/log/wtmp.ascii
>/var/log/wtmp
You can do a
who /var/log/wtmp | head -gazillion
to get part of the output. You can rotate the ascii version, etc.
Anyway, the who command is the way to get readable data
without resorting to C. The command who with no filename reads utmp
and wtmp accumulates utmp data for processes no longer running.
