Okay, so here's an overview of what my Nostr shell scripts will do, at least initially:

1. Retrieve the user's private key and relay list.

2. Send the respective event with the appropriate arguments to all available relays in the list either via websocat or /dev/tcp.

3. Clear the private key and relay list from memory.

4. Exit.

Note that these scripts won't be a full featured client like nostr-console, but specific task-based commands like nostr-note, nostr-follow, nostr-zap, etc.
