From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How are you parsing JSON on the command line? (lemmy.world)

I want to extract and process the metadata from PNG images and the first line of .safetensors files for LLM's and LoRA's. I could spend ages farting around with sed or awk but formats of files are constantly changing. I'd like a faster way to see a summary of training and a few other details when they are available.

jq, and its Yaml sibling, yq.

I have a very handy command in my .vimrc for this -

command! JSON setlocal filetype=json | %!jq .

Anytime I'm in a json file that isn't formatted it's as simple as typing :JSON to have it all sorted.

Specifically this version of yq - there are other versions bundled with distros that look and act very differently and lack the potency of this version.

Seriously, can't get those 15 minutes back.

And there is htmlq too, if you ever need to scrape some stuff from a website :)

Naw, everybody knows that you have to use regex for that
