I forgot nostcat: https://github.com/blakejakopovic/nostcat

Example:

$ nostril query -k 0 -l 1 -a $(bech32 -d npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s | xxd -p -c100) |
nostcat wss://relay.damus.io |
jq '.[2].content | fromjson'

Returns:

{"banner":"https://nostr.build/i/3d6f22d45d95ecc2c19b1acdec57aa15f2dba9c423b536e26fc62707c125f557.jpg","display_name":"William","name":"jb55","picture":"https://cdn.jb55.com/img/red-me.jpg","nip05":"_@jb55.com","lud16":"jb...@jb55.com","website":"https://damus.io","about":"I made damus, npubs and zaps. banned by apple & the ccp. my notes are not for sale."}

nostril-query is a script in my nostril repo.

$ nostril query -k 0 -l 1 -a $(bech32 -d npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s | xxd -p -c100)
["REQ", "nostril-query", {"authors": ["32e1827635450ebb3c5a7d12c1f8e7b2b514439ac10a67eef3d9fd9c5c68e245"], "limit": 1, "kinds": [0]}]

as you can see nostril query generates queries for nostcat.

Where bech32 is https://github.com/cmoog/bech32

I wrapped bech32 with a script called npub:

#!/bin/sh sh
bech32 -d "$@" | xxd -p -c100

So you can just do:

$ nostril query -k 0 -l 1 -a $(npub npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s)

Although I should eventually just add nevent/npub/note/nprofile support to nostril...

This is awesome, thank you very much for taking the time to show me these! Those tools will definitely come in handy during development.

I was able to successfully install these tools. I will definitively be using them!

Cheers,
Daniel
