How many links are buried inside a large PDF — and where do they really go?

I extracted every URL from a 291-page Voron assembly manual, isolated shortlinks, resolved redirects, and built a TSV [tab-delimited] manifest with video duration + titles using:

pdfgrep
awk
curl
yt-dlp

Netcat was, and still is, the networking Swiss army knife.
Before modern pentesting suites and flashy UIs, netcat quietly did it all. Reverse shells, raw TCP file transfers, port scanning, even makeshift chat servers. All from a single terminal. Lightweight and deadly in skilled hands, it is just as useful today as it was decades ago.

Finally time to boast post about a bday gift I bought myself:

"Ed Mastery" by @mwlucas - a masterpiece for those of us too lazy to learn only reading the source and man(1).

Really enjoying my Friday night!
Working on my ed(1) in the sh(1)!
