A simple and extensible shell script for managing your todo.txt file.

There is this well hidden command line tool called "column" that allows you to align the data nicely in properly sized columns. Combine this with a pager like less and we have a nice prototype already

I figured out how to run a SQL query directly against a CSV file using the sqlite3 command-line utility:

'SELECT passenger_count, COUNT(*), AVG(total_amount) FROM taxi GROUP BY passenger_count'

Everything is a file under Linux and ls* and friends can help you to dig out more information from the system than you originally thought. These Linux tips may come in handy when you need to find out information quickly without going through /proc or sysfs.

A fully-modern text-based browser, rendering to TTY and browsers

gron is a self-contained Go executable you can download from here on GitHub. In the UNIX tradition, gron does one thing well: it flattens JSON into a structure that's easily processed by shell tools, line by line.

Make JSON greppable!

gron transforms JSON into discrete assignments to make it easier to grep for what you want and see the absolute 'path' to it. It eases the exploration of APIs that return large blobs of JSON but have terrible documentation.

q -- a tiny command line DNS client with support for UDP, TCP, DoT, DoH, DoQ and ODoH.

Oh-heck is a CLI tool that takes natural language input and outputs a terminal command using GPT-3.

Glow is a terminal based markdown reader designed from the ground up to bring out the beauty—and power—of the CLI.

Use it to discover markdown files, read documentation directly on the command line and stash markdown files to your own private collection so you can read them anywhere. Glow will find local markdown files in subdirectories or a local Git repository.

By the way, all data stashed is encrypted end-to-end: only you can decrypt it. More on that below.
