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.

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.

i'm assuming that command line means bash; in which case jq and regex are your friends.

I found a Python project that does enough for my needs. Jq looks super powerful though. Thanks. I managed to get yq working for PNG's, but I had trouble with both jq and yq with safetensor files. I couldn't figure out how to parse a string embedded in an inconsistent starting binary, and with massive files. I could get in and grab the first line with head. I tried some stuff with expansions, but that didn't work and sent me looking for others that have solved the issue better than myself.
