I am doing this operation for each line in my file. So its taking very long time to process more than 1000 records.

Is there any alternative way to write the above if statement
Perhaps this. Not tested tho'
Code:
while read line
do
  if [[ $line == "$companyHdrRecord*" ]] ; then
    echo $line
  fi
done < input.txt
