I just thought about the above startup options. Here's the freshclam.sh
script I use with the 3 passed parameters shown in the startup:

#!/bin/bash
usage () {
 echo "Usage: freshclam.sh [update|failed|outdated]"
 exit 1
}
if [ doo"$1" = 'doo' ] ; then
  usage
else
 DO=$1
fi
perlcln () {
RTN=`echo $V|perl -pe 's/%(..)/pack("c",hex($1))/eg'`
RTN=$RTN$EM0
}
DATE=`date`
"M0="
EM2=`echo "Tail (-n10) of clamav.upd in /var/log/clamav"`
cnt=7
until [ $cnt -le 0 ]
 do
 CNT=`tail -n"$cnt" /var/log/clamav/clamav.upd|head -n1`
 V=$CNT
 perlcln
 CNT=$RTN
 echo $CNT >> /tmp/zzxxaa
 cnt=$(($cnt-1))
done
FL=`cat /tmp/zzxxaa`
if [ $DO = 'update' ] ; then
    EM1=`printf "Freshclam update ran ($DATE)"`
  elif [ $DO = 'failed' ] ; then
    EM1=`printf "Freshclam update failed ($DATE)"`
  else
  usage
fi
EMALL=$EM1$EM0$EM0$EM2$EM0$EM3$EM0$FL
echo $EMALL|mail -s "FreshClam $DO" karlp
rm /tmp/zzxxaa
exit 0

Yes, I know, it's not very elegant, but hey, I'm a problem solver, not a
programmer and it seems to work... But, I'm not opposed to being told how to
do it better. Any takers?
