Afraid I am still finding myself lost. Here is what I have right now. I tried creating a second file and doing the read on that, but still no variable being passed in my echo.

Code:
tail -2 filename.txt | tr "\n" " " > filename2.txt
tail filename2.txt | read a b
echo $b
if [ $a -gt 400 ] && [ $b -gt 400 ]; then
  touch filename.txt
fi
