Count number of lines in a file

find . -type f -exec cat {} ; | wc -l

and if you don’t want repeats

find . -type f -exec cat {} ; | egrep \S | wc -l

I even thought about cat, but I ended up doing something like:

total=0
for i in $( find -H . -type f ); do
  temp=$( wc -l "$i" | cut -f 1 -d  )
  if [ $temp > 0 ]; then
    total=$(($total+$temp))
  fi
  echo $total
done
echo $total
