Automatic downloading files from list with existence check

#!/bin/bash
# This script downloads files from the list with name file*.list
# Each row in any of the file*.list must be full URL like
# http://example.com/example.file
# Also if not all of files were downloaded it can re-check and download
# the files that were missed ("mirroring" function).
# To make this script work dont forget to create list of URLs with name file.list
# Or you may change the "listname" variable to suit your needs.

listname=file*.list

let rownum=$(grep -o "/" <<<"$line" | wc -l)+1
namev=$(echo $line | awk -F"/" '{ print '"$"$rownum' }')
