After hitting the send button I realized that there is a simpler
solution using a classical Unix pipe:
#!/bin/sh
added_date="`date +%Y%m%d`"
hits_rpt="hits_rpt"
hits_new="hits.yes"
hits_no="hits.no"
truncate -s 0 $hits_rpt $hits_new $hits_no
ippool -l -d -m probing_ips > $hits_rpt 2> /dev/null
tail -n +4 $hits_rpt | # start at 4th line
paste - - | # join two consecutive lines
sed -e 's:^ *::' -e 's:/32::' | # remove spaces at the beginning
# and "/32" suffix from IP address
cut -w -f 2,4 | # extract IP and Hits from combined line
# (at 2nd and 4th field)
while read ip hits # read IP and Hits from each line
do # and do your work
if [ "$hits" -gt 0 ]; then
echo "$added_date ${ip};" >> $hits_new
fi
echo "$hits ${ip};" >> $hits_no
done
exit 0
If the "ippool" uses tabs in the output just add "tr '\t' ' '" between
the "paste" and "sed" step.
Bye, Andreas
