✅استخراج تمام ایمیل‌ها از یک فایل!

🔹یک ترفند ساده اما قدرتمند: استخراج تمام آدرس‌های ایمیل از یک فایل متنی با یک دستور. بدون پایتون یا دردسر اضافی.

🔸فرض کنید فایلی به نام data.txt داریم. برای استخراج تمام آدرس‌های ایمیل از آن، از grep به همراه یک عبارت منظم استفاده می‌کنیم:
grep -Eo '[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,}' data.txt
🔸آپشن -E عبارات منظم توسعه‌یافته را فعال می‌کند، -o فقط تطابق‌ها را نمایش می‌دهد و این عبارت منظم اکثر ایمیل‌های معتبر را پوشش می‌دهد.

🔹اگر می‌خواهید نتیجه را در یک فایل ذخیره کنید:
grep -Eo '[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,}' data.txt > emails.txt
🔹اگر نیاز به جمع‌آوری سریع یک پایگاه داده برای تجزیه و تحلیل، اشکال‌زدایی یا فیلتر کردن دارید، مناسب است.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.
