escape='s/\([[()\] -]\)/\\&/g'
p=$(echo $path | sed "$escape")

# Command

while read line; do
    ep=$(echo "$line" | grep -Po "$num" | tr -d " ")

    if [[ $ep -ge "$1" ]]; then
        v=$(echo "$videos$line" | sed "$escape")
        s=$(echo "$subs$sub$ep.srt" | sed "$escape")
        script+=("--{" "$p$v" "--sub-file=$p$s" "--}")
    fi
done < <(ls "$videos" | grep -P "$video")
