Hmm.. that's a good tip..
I figure that since I am supposed to have like 6 fields per line, I can do this
NoRecords=`cat $1 | wc -l`
TotalNoFields=`awk -F':' '{ total = total + NF }; END {print total}' $1`
let FieldsPerLine=$TotalNoFields/$NoRecords
if [ $FieldsPerLine -ne "6" ]; then
echo "Incorrect Number of Fields"
usage
exit 1
fi
Cool.. That's one thing solved.
