Xonsh is a Python-powered, cross-platform, Unix-gazing shell language and command prompt.

Xonsh is meant for the daily use of experts and novices alike.

Xonsh is significantly different from most other shells or shell tools.

Prompt-toolkit: advanced readline library, line-editing.

Xonsh integrates with Jupyter, an in-browser REPL, enabling the use of xonsh in jupyter notebooks.

Xonsh is a cross-platform, Python-powered, Unix shell language and command prompt designed for the use of experts and novices alike.

The Xonsh language is a Python 3.4+ superset and it features additional shell primitives that make it familiar to working from IPython and Bash.

Xonsh is easily scriptable and it allows you to mix both command prompt and python syntax coupled with a rich standard library, man-page completion, typed variables, and syntax highlighting, among other features.

Xonsh is significantly different from other shell tools as can be seen in comparison to other command prompts like Bash, zsh, fish, IPython, and plumbum.

Xonsh has certain requirements to run including Python v3.4+, PLY, and prompt-toolkit.

I don't know which shell tools and command prompt you enjoy using the most but Xonsh seems to have won the hearts of many users for reasons experts celebrate over.

Rwtxt is an open-source website where you can store any text online for easy sharing and quick recall.

Rwtxt builds off cowyo, a similar app I made previously.

In improving with rwtxt I aimed to avoid second-system syndrome: I got rid of features I never used in cowyo, while integrating a useful new feature not available previously: you can create domains.

You can share rwtxt links to read them on another computer.

Rwtxt is organized in domains - places where you can privately or publicly store your text.

Only people with the domain password can edit in your domain - making rwtxt useful as a password-protected wiki.

You can easily install and run rwtxt on your own computer.

Lazygal is another static Web gallery generator. It is command line based, uses a reusable engine and is lazy, meaning that it regenerates only parts that have to be regenerated. There is support for many interesting features like subgalleries, EXIF information, theming, and custom folder meta data. Included themes are pure XHTML and CSS.

Liquid Prompt gives you a nicely displayed prompt with useful information when you need it. It shows you what you need when you need it.

You will notice what changes when it changes, saving time and frustration. You can even use it with your favorite shell – Bash or zsh.

Terminal utility that allows you to use words coming from the standard input to create a nice selection window just below the cursor. Once done, your selection will be sent to standard output.

Toolkit for Text Generation and Beyond. Contribute to asyml/texar development by creating an account on GitHub.

Features:

• Cross-platform support for Linux and Mac
• Automation (so there's no need to remember to click "backup")
• Point-in-time recovery (or something close) so if you accidentally delete a file but don't notice until later, it's still recoverable
• Low cost
• Replicated data store for backup sets, so data exists in more than one place (i.e., not just backing up to a local USB drive)
• Encryption in case the backup files fall into the wrong hands

Open Automatic Number Plate Recognition on Smartphones (former UIT-ANPR).

Flameshot is an easy to use, open source, Qt-based screenshot utility which is adept at capturing custom areas of a desktop.

Rolo keeps track of your contacts and display them to you with a text-based menu.

Rolo strives to be a well-constructed tool for complimenting text-based email programs-such as mutt. It utilizes the vCard version 3.0 format for storing its contacts and it interfaces with the end-user through a NCurses front-end.

Building command line tools in Bash is an extremely tedious and somewhat enigmatic task. There's quite a bit of boilerplate code you're going to have to write if you want your script to do more than just one thing, which will only clutter your script. In addition, your scripts will likely never be able to reference good code you've written from old scripts.

Ash helps you get rid of all of your boilerplate by letting you call functions directly from the command line, while also providing a modular approach to scripting which will allow you to share code between scripts.

You are able to build a module independently that functions as a CLI or as a library (or any combination of the two), and easily share your module with the world.

restic is a program that does backups right.

Features

• Easy: Doing backups should be a frictionless process, otherwise you are tempted to skip it. Restic should be easy to configure and use.
• Fast: Backing up your data with restic should only be limited by your network or hard disk bandwidth so that you can backup your files every day.
• Verifiable: restic enables you to easily verify that all data can be restored.
• Secure: Restic uses cryptography to guarantee confidentiality and integrity of your data. The location where the backup data is stored is assumed to be an untrusted environment.
• Efficient: With the growth of data, additional snapshots should only take the storage of the actual increment.
• Free: restic is free software and licensed under the BSD 2-Clause License and actively developed on GitHub.
