Fastest way to check 1000’s of url’s to find out if they are active?

I need to check over 70,000 url’s to make sure they are still active for our listings website. Is there a way to do it without having to click each and every url, wait for it to load and visually check it? I am doing it right now in batches of 10 but it is still taking me a ridiculous amount of time to get through them all. Not to mention, sometimes these buy a domain site looks very close to an active website. I am using a Mac if that makes a difference.
Any help would be deeply appreciated.
Thank you!

Any scripting lanugae will help, shell script, python etc. Use for loop.

That’s the thing, I don’t know anything about scripting so I was hoping someone would help me out on this issue. Maybe? Hopefully? Fingers crossed…
