Typically this is done by the logclean command in crontab every Sunday.

However this involves taking a copy of the current log file and compressing it. Considering the size of the file, you might want to use the /usr/sbin/acct/nulladm command instead.

If you want to be really safe, then you could turn off accounting first, e.g.:

/sbin/init.d/acct stop
/usr/sbin/acct/nulladm /var/adm/wtmp
/sbin/init.d/acct start

Copy existing to new file and compress it

run "/usr/sbin/acct/nulladm /var/adm/wtmp"

to Clear /var/adm/wtmp
you can insert this command it to crontab
