#!/bin/bash
NOW=$( date +"%s" )
while read MONTH DAY TIME DATA
do
    THEN=$( date -d "$MONTH $DAY $TIME" +"%s" )
        COUNT=$((COUNT+1))
done < $1
echo $COUNT

Open in new window

I want to count all the lines that begin with a valid date.  This code works if a line begins with a valid date but if it does not then it returns an error.
