fx is the best JSON viewer you'll ever use

iff-so-fancy strives to make your diffs human readable instead of machine readable. This helps improve code quality and helps you spot defects faster.

dog is a command-line DNS client, like dig. It has colourful output, understands normal command-line argument syntax, supports the DNS-over-TLS and DNS-over-HTTPS protocols, and can emit JSON.

xh is a friendly and fast tool for sending HTTP requests. It reimplements as much as possible of HTTPie's excellent design, with a focus on improved performance.

procs is a replacement for ps written in Rust.

Colored and human-readable output
    Automatic theme detection based on terminal background
Multi-column keyword search
Some additional information which are not supported by ps
    TCP/UDP port
    Read/Write throughput
    Docker container name
    More memory information
Pager support
Watch mode (like top)

Glances is a cross-platform monitoring tool which aims to present a large amount of monitoring information through a curses or Web based interface. The information dynamically adapts depending on the size of the user interface.

A customizable cross-platform graphical process/system monitor for the terminal.

McFly replaces your default ctrl-r shell history search with an intelligent search engine that takes into account your working directory and the context of recently executed commands. McFly's suggestions are prioritized in real time with a small neural network.

A small command-line application to view images from the terminal written in Rust. It is basically the front-end of viuer. It uses either iTerm or Kitty graphics protocol, if supported. If not, lower half blocks (▄ or \u2584) are displayed instead.

Based on the value of $TERM, viuer decides which protocol to use. For half blocks, $COLORTERM is inspected. If it contains either truecolor or 24bit, truecolor (16 million colors) will be used. If not, it will fallback to using only ansi256. A nice explanation can be found in this gist.

Had JSON been around when I was born in the 1970’s Ken Thompson and Dennis Ritchie may very well have embraced it as a recommended output format to help programs “do one thing well” in a pipeline.

To that end, I argue that linux and all of its supporting GNU and non-GNU utilities should offer JSON output options. We already see some limited support of this in systemctl and the iproute2 utilities like ip where you can output in JSON format with the -j option.

jc JSONifies the output of many CLI tools and file-types for easier parsing in scripts. See the Parsers section for supported commands and file-types.

In simple words, ssh-audit is a tool for ssh server and client auditing. For example, you can use this tool:

Scan for OpenSSH server and client config for security issues
Make sure the correct and recommended algorithm is used by your Linux and Unix boxes
Check for OpenSSH banners and recognize device or software and operating system
Lookup for ssh key exchange, host-keys, encryption, and message authentication code algorithms
Alert developers and sysadmin about config issues, weak/legacy algorithms, and features used by SSH
Historical information from OpenSSH, Dropbear SSH, and libssh
Policy scans to ensure adherence to a hardened/standard configuration

Ncdu is a disk usage analyzer with an ncurses interface. It is designed to find space hogs on a remote server where you don’t have an entire graphical setup available, but it is a useful tool even on regular desktop systems. Ncdu aims to be fast, simple and easy to use, and should be able to run in any minimal POSIX-like environment with ncurses installed.

wttr.in — the right way to check curl the weather!

wttr.in is a console-oriented weather forecast service that supports various information representation methods like terminal-oriented ANSI-sequences for console HTTP clients (curl, httpie, or wget), HTML for web browsers, or PNG for graphical viewers.

googler is a power tool to Google (web, news, videos and site search) from the command-line. It shows the title, URL and abstract for each result, which can be directly opened in a browser from the terminal. Results are fetched in pages (with page navigation). Supports sequential searches in a single googler instance.

googler was initially written to cater to headless servers without X. You can integrate it with a text-based browser. However, it has grown into a very handy and flexible utility that delivers much more. For example, fetch any number of results or start anywhere, limit search by any duration, define aliases to google search any number of websites, switch domains easily... all of this in a very clean interface without ads or stray URLs. The shell completion scripts make sure you don't need to remember any options.

musikcube is a fully functional terminal-based music player, library, and streaming audio server that runs natively on Windows, macOS, and Linux. it also runs well on a Raspberry Pi with a custom DAC (e.g. IQaudIO DAC+, HiFiBerry DAC+ and others), and can output 24bit/192k audio comfortably.

Resource monitor that shows usage and stats for processor, memory, disks, network and processes.

C++ version and continuation of bashtop and bpytop.

A friendly reminder that if you need to sort IP addresses in numerical order by octet, you can use sort -V, which is intended to sort software versions…but works just as well for IP addresses.

Guardian Agent (now in beta) allows users to securely empower remote hosts to take actions on their behalf, using their SSH credentials. It allows Mosh and SSH users to enable agent forwarding for every connection, even to hosts they may not fully trust.

Guardian Agent is an alternative to traditional ssh-agent forwarding, which can only safely be enabled when connecting to trusted hosts. The traditional ssh-agent protocol doesn't give the agent information about which host is asking to perform a command on the user's behalf, which server that hosts wants to connect to, or which command the host wants to perform:

Include
Include the specified configuration file(s). Multiple pathnames may be specified and each pathname may contain glob(3) wildcards and, for user configurations, shell-like
``~'' references to user home directories. Files without absolute paths are assumed to be in ~/.ssh if included in a user configuration file or /etc/ssh if included from
the system configuration file. Include directive may appear inside a Match or Host block to perform conditional inclusion.

I had my Include statement trailing a Host directive so it was being included into that Host's config.
