    If you’re going to use jq to manipulate JSON I’d recommend a helper CLI tool like ijq. It allows you to experiment without needing too lines in your terminal history.

    I’m curious if anyone else has considered using nushell for these things? Probably not for everything (or to replace one’s shell) but it definitely is simpler for basic tasks.

      That’s the primary value offer of nushell so at least people who made it considered it I’d say.

    I asked an LLM to write a jq scriptlet for me today. It wasn’t even complicated, it just beat working it out/trying to craft the write string to search Stackoverflow for.

      I tried and failed to get an LLM to write jq code to do a regex based matcher for finding if one json object was a subset of another.

      Gave up and learned it enough to get it going. jq is nutso powerful.

        I don’t understand how regex comes into it? Sounds tricky though!

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.
