Answer 1

I would suggest processing using awk:

for i in $FILES
do
    echo -n \""$i\": "
    awk 'BEGIN {
           output="";
           outputlength=0
         }
         /(^ *[0-9]+)/ {                                    # process only lines that start with a number
           if (length(substr($10, 2)) > outputlength) {     # if line has more hashes, store it
             output=$0;
             outputlength=length(substr($10, 2))
           }
         }
         END {
           print output                                     # output the resulting line
         }' "$i"
done
