Mastering jq
Mastering jq
This is the first part of an ongoing series on mastering jq. jq is a valuable tool that every fast coder has in their tool chest. It contains depths of immense power. In part 1, we'll start off with the basics.
I don't know if we should call someone a master of jq if they do
echo '{"k1": [{"k2": [9]}]}' | jq '.k1 | .[0] | .k2 | .[0]'
Instead of just
echo '{"k1": [{"k2": [9]}]}' | jq '.k1[0].k2[0]'
The first step to mastery is RTFM: https://jqlang.org/manual/
oh hey, a project that actually has a manual to read
If you're going to use
jqto manipulate JSON I'd recommend a helper CLI tool likeijq. 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
jqscriptlet for me today. It wasn't even complicated, it just beat working it out/trying to craft the write string to search Stackoverflow for.
