[SOLVED] Grep: command for getting a key value from another command

Issue

I am creating a kafka instance creation script and I want to gather the bootstrap server from a describe command.

The command to gather the kafka instance details is.

rhoas kafka describe

the output looks something like this

"admin_api_server_url": "server-address",
  "billing_model": "standard",
  "bootstrap_server_host": "foobar",
  "browser_url": "browser-url",
  "cloud_provider": "aws",

What I am looking for is a grep command that will return just foobar from "bootstrap_server_host"

I have tried rhoas kafka describe | grep bootstrap_server_host which returns the whole line.

"bootstrap_server_host": "foobar",

I just want foobar by itself. Thanks

Solution

rhoas kafka describe | grep bootstrap_server_host | cut -d \" -f 4
