bandwhich sniffs a given network interface and records IP packet size, cross referencing it with the /proc filesystem on linux or lsof on MacOS. It is responsive to the terminal window size, displaying less info if there is no room for it. It will also attempt to resolve ips to their host name in the background using reverse DNS on a best effort basis.

This looks much better than me fumbling through lsof’s man page for ten minutes and then giving up.

Quickly view and search notifications, mark notifications as read (or unsubscribe entirely), add comments to issues (and more) all from the warm glow of your trusty terminal.

Inspired by a similar post by Ben Boyter this a list of useful command line tools that I use. It’s not a list of every tool I use. These are tools that are new or typically not part of a standard POSIX command line environment.

By “illustrated” he means there’s a screencap of the tools in action.

Liran Tal:

I wrote this tiny module thing that allows you to quickly check if a website is running vulnerable JS libs straight from the terminal. You’d be surprised how many websites are still running old and vulnerable versions of jQuery, Bootstrap, Angular and others.

Use it responsibly ;-)

navi allows you to browse through cheatsheets (that you may write yourself or download from maintainers) and execute commands, prompting for argument values.

Because the “right” way to do many things begins with curl 😆

Translate Shell (formerly Google Translate CLI) is a command-line translator powered by Google Translate (default), Bing Translator, Yandex.Translate, and Apertium

Nothing succeeds like success.

readme-md-generator is able to read your environment (package.json, git config…) to suggest you default answers during the README.md creation process

Nice to see it using All Contributors.

I 💚 youtube-dl, but I use it just infrequently enough that I can NOT remember which flags to use. I guess I’m not the only one!

Send email via Amazon SES with minimal fuss. Once you have it all set up, sending email with Maildown is as easy as:

maildown send christopherdavies553@gmail.com "my email subject" -f "email.md" recipient1@gmail.com recipient2@gmail.com

Supports Markdown, in case you were wondering…

If you would’ve bet me $100 back when React first started getting popular that in the years to come people would be crafting interactive command-line interfaces with the UI framework… well.. you’d have $100 more than I would right about now.

Despite all the recent hype, setting up a new TypeScript (x React) library can be tough. Between Rollup, Jest, tsconfig, Yarn resolutions, TSLint, and getting VSCode to play nicely….there is just a whole lot of stuff to do (and things to screw up). TSDX is a zero-config CLI that helps you develop, test, and publish modern TypeScript packages with ease–so you can focus on your awesome new library and not waste another afternoon on the configuration.

WebAssembly is a powerful tool for bringing command line utilities to the web and giving people the chance to tinker with tools.

Yet another excellent use case for Wasm.

Could this be the future of writing interactive CLI tools? If you know React you know Ink.

Ink is a library for building and testing command-line applications using React components. Since it acts as a React renderer, you can use everything that React has to offer: hooks, class components, state, context, everything. Ink lets you build interactive and beautiful CLIs in no time.

Lightweight and without any external dependencies qoa enables you to receive various types of user input through a set of intuitive, interactive & verbose command-line prompts. The library utilizes a simple & minimal usage syntax and contains 7 configurable console interfaces, such as plain text, confirmation & password/secret prompts as well as single keypress, quiz & multiple-choice navigable menus.

You can search from commits, inspect indvidual files and changes in the commits, see ahead/behind commits etc. It is an alternative and interactive way to explore the commit history. Also, you can explore your current state by investigating diffs, stage your changes and commit them.

An alternative command-line client for SQLite. Provides intuitive auto-completion against table names and columns. It’s written in Python, so you can get it with a pip install litecli

Any git repository contains a tonne of information about commits, contributors, and files. Extracting this information is not always trivial, mostly because of a gadzillion options to a gadzillion git commands – I don’t think there is a single person alive who knows them all. Probably not even Linus Torvalds himself :)

Truth. Clone the repo here and make install or brew install git-quick-stats if you’re on macOS.

We’ve been chronicling Daniel’s work on #curl for some time now. December 11, 2018 will be Daniel’s final official day at Mozilla. He assures us that his work on curl will continue, saying this in regards to his time dedicated to curl and where he works for his full-time income, “I don’t think my choice of future employer should have to affect that negatively too much, except of course in periods.”

Here are the main points from Daniel (but you should certainly dig into the details):

1. It’s been five great years, but now it is time for me to move on and try something else.
2. …lots of the HTTP/2 development and the publication of that was made while I was employed by Mozilla and I fondly participated in that.
3. …we’re also losing Mozilla as a primary sponsor of the curl project, since that was made up of them allowing me to spend some of my work days on curl and that’s now over.
4. I will continue to follow and work with HTTP and other internet protocols very closely.
5. The future is bright but unknown! “I don’t yet know what to do next.”

q is a command line tool that allows direct execution of SQL-like queries on CSVs/TSVs (and any other tabular text files). q treats ordinary files as database tables, and supports all SQL constructs, such as WHERE, GROUP BY, JOINs etc. It supports automatic column name and column type detection, and provides full support for multiple encodings.

An example of using q to count distinct values of a specific field (uuid of clicks data)

q -H -t "SELECT COUNT(DISTINCT(uuid)) FROM ./clicks.csv"

graph-cli is designed to be highly configurable for easy and detailed graph generation. It has many flags to acquire this detail and uses reasonable defaults to avoid bothering the user. It also leverages chaining, so you can create complex graphs from multiple CSV files.

Meet up a.k.a. the Ultimate Plumber:

The main goal of the Ultimate Plumber is to help interactively and incrementally explore textual data in Linux, by making it easier to quickly build complex pipelines, thanks to a fast feedback loop. This is achieved by boosting any typical Linux text-processing utils such as grep, sort, cut, paste, awk, wc, perl, etc., etc., by providing a quick, interactive, scrollable preview of their results.

mdncomp gives web developers a handy tool to see browser compatibility data right on the CLI. It currently covers APIs, CSS, HTML, HTTP, JavaScript, MathML, SVG, WebDriver, WebExtensions, XPath and XSLT.

dategrep reads a file and prints every line with a timestamp that falls into a user defined time range. When invoked on a normal file, dategrep uses a binary search to find the first matching line.

The usefulness of this is perhaps best understood by seeing a few examples:

dategrep --start "12:00" --end "12:15" syslog
dategrep --end "12:15" --format "%b %d %H:%M:%S" syslog
dategrep --last-minutes 5 syslog
cat syslog | dategrep --end "12:15"

Looks cool, but mind the disclaimer:

The project is still under alpha, there are lots of things already done, but there is also a lot of work to do! If you want to help, please contact me under marcelocamargo@linuxmail.org or create an issue! Working in community, we can soon have a CLI client as complete as the web one!
