: is a builtin shell command that does nothing. Thus piping its output (nothing) to /var/run/utmp has the effect of creating /var/run/utmp if absent, and truncating it to zero length if already present. The result is that when the system boot up, /var/run/utmp is present and empty prior to any logins. Regards, Roger -- .''`.
