update never stop running

[LeonardoGentile]

Hello, thanks for this.
I'm trying to update the lists using ./update however it seems I'm not able to.
I've tried several times and it seems the script take a huge amount of time around this block

for domain in $(cat $tmp); do
    result=`dig +short mx $domain`
    echo $result
    if [ -n "$result" ]; then
        echo $domain >> $confirmed
    fi
done

I'm not exactly sure what it is doing but it seems to me it is stuck in a cycle somehow

./update exits cleanly for me on OSX in just under one minute. Can you add a set -x to the top of the script to see what it's doing? The code block you posted does a DNS lookup on each domain in the list so it's likely to take a bit of time.

@willwhite thanks!
I don't know why but this time it worked, I could see the output, it took around 10+ minutes, probably the last time I was behind a firewall or I've stopped the script before it ended, I don't know what else to think.

Anyway my connection is not usually slow so I don't know why it took me 10x times compared to your test..

I'm on OSX, iterm2, the standard (presintalled) sh is 3.2.53 but recently installed bash version 4.3.42.
Lunched the script with both sh and bash and the result is still the same
