7.13 How can I avoid those annoying copyright notices on login?

The following code in /etc/profile prints the copyright notice the first
time each user logs in:

        NUMLOGINS=`/etc/last -2 $LOGNAME | wc -l`
        if [ $NUMLOGINS -lt 2 ]
        then
                cat /etc/copyright
        fi

And, for /etc/csh.login:

set NUMLOGINS=`/etc/last -2 $LOGNAME | wc -l`
if ( $NUMLOGINS<2 ) cat /etc/copyright

(Actually, each user will get the copyright on their first login after each
time the /etc/wtmp file is pruned, but that needn't be often.)
