Do one thing well. For command-line utilities to do their one thing “well” they must include standardized machine-readable output. Linux and all of its supporting GNU and non-GNU utilities should offer JSON output options.
In this article I give a quick snapshot of what it’s like to work with JSON in various traditional and next generation shells. Traditional shells like Bash and Windows Command Prompt (cmd.exe) don’t have built-in JSON support and require 3rd party utilities. Newer shells like NGS, Nushell, Oil, Elvish, Murex, and PowerShell have JSON serialization/deserialization…
Effectively use JSON data at the command line with jc, jq, and Bash. This article provides practical examples of how to improve your scripts with JSON.
In this multi-part blog series, I will describe some microservice security design patterns to implement micro-segmentation and deep inspection in the interior of your Kubernetes cluster to further secure your microservice applications, not just the cluster. I will also demonstrate the design patterns with working Proof of Concept deployments that you can use as a…
jello works similarly to jq but uses the python interpreter, so you can iterate with loops, comprehensions, variables, expressions, etc. just like you would in a full-fledged python script.
jtbl is simple and elegant. It just takes in piped JSON or JSON Lines data and prints a table. There’s only one option to turn on column truncation vs. wrapping columns if the terminal width is too narrow to display the complete table. It ‘does the right thing’.
Tips and tricks for using JC interactively, in scripts, and in automation. In Part 2 we look at using JC to parse URLs, POSIX paths, and git log output.

We can apply concepts from application architecture (SOA and Microservices) to more effectively build automation into our cybersecurity stacks. Orchestration and Choreography both have important roles to play.
A friend of mine pointed me to a twitter thread on how to explain Kubernetes to a five year old. Since I have a two year old, this immediately popped …
In this post we’ll configure a Security Sidecar Pattern which will provide application level protection and micro-segmentation within the Kubernetes cluster.
