#unixtools — Public Fediverse posts

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

A practical method for auditing technical PDFs and embedded media.

#ProTip #UnixTools

Boost post from my employer: Want to #visualize the semantic environment of a file or a graph of all imported modules? You can write a #Javascript parser and extract the AST. A quicker way is this lean #degrapher our colleague Arne crafted with #unixtools. See how it's done: https://blog.disy.net/depgrapher/ — me blogging for #work :-)

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)!
