Download with wget using a .list of urls. Every download happens in parallel and every .list has it's own process

parallel wget from lists located in many folders

#!/bin/bash

path=$(realpath ${1:-.})
parallel=${2:-8}
directory=
for list in $(find "$path" -wholename "*/.list")
do
        # .ignore file exists?
        directory="${list%/*}"
        if [ -f "$directory"/.ignore ]; then
                continue
        fi
        cd "$directory"
        ( cat $list | xargs -I % -n 1 -P $parallel wget -t 1 --header="Accept: text/html" --user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0" ‐‐referer="https://www.google.com" % ) &   
        cd "$path"
done
