Re: Delete Next Blank Line IFF Current Line is Less than 80 Characters

As you are in bash, you could use something like that:

#!/bin/bash

DEL=false # might delete a empty first line
while read -r line
do
     if $DEL  && [[ -z "$line" ]]
     then
             DEL=false # and skip line
     else
         L=$(echo "$line" | wc -m )
         [[ $L -lt 80 ]] && DEL=true || DEL=false
         echo "$line" # print line
     fi
done < "$1"
