GNU Bash vs Nu Shell: What are the differences?

Introduction

In this Markdown code, I will provide a comparison of the key differences between GNU Bash and Nu Shell.

Execution Model: GNU Bash follows an imperative execution model where the user provides a series of commands to be executed in a sequential manner. On the other hand, Nu Shell follows a data-oriented execution model where data flows through pipelines and commands are applied to the data as it passes through.
Data Structures: GNU Bash primarily operates on strings, making it suitable for text processing tasks. However, Nu Shell introduces structured data as first-class citizens, allowing users to manipulate and transform data using tables, records, and columns.
Command Syntax: GNU Bash follows a traditional Unix shell syntax with a combination of commands, flags, and arguments. Nu Shell opts for a more modern and user-friendly command syntax, with clearer subcommand names and the ability to chain commands using the pipe operator (|).
Extensibility: GNU Bash offers extensibility through shell scripts, where users can write custom scripts to automate tasks. Nu Shell takes a different approach by providing a plugin system, allowing users to extend the functionality of the shell with additional commands and data processing operations.
Error Handling: GNU Bash handles errors in a straightforward manner, where a failed command in a script will stop the execution. In contrast, Nu Shell follows a more resilient approach by continuing with the execution even if a command fails, providing users with more flexibility in handling errors within scripts.
Parallel Execution: GNU Bash does not inherently support parallel execution of commands. Nu Shell, on the other hand, provides built-in support for parallel execution, allowing users to leverage multiple cores and CPUs to run commands concurrently, resulting in improved performance for computationally intensive tasks.

In summary, GNU Bash and Nu Shell differ in their execution model, data structures, command syntax, extensibility, error handling, and support for parallel execution. These differences make Nu Shell a more modern and powerful shell for data manipulation and processing tasks.

Review

If you have a file (demo.txt) that has 3 columns:

Column-1    Column-2    Column-3
Row-1a      Row-2a      Row-3a         
Row-1b      Row-2b      Row-3b
Row-1c      Row-2c      Row-3c
Row-1d      Row-2d      Row-3d
Row-1e      Row-2e      Row-3e

and you want to only view the first column of the file in your CLI, run the following:

awk {'print $1'} demo.txt

Column-1
Row-1a
Row-1b
Row-1c
Row-1d
Row-1e

If you want to print the second column of demo.txt, just replace $1 with $2

Detailed Comparison

GNU Bash	Nu Shell
The Bourne Again SHell is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard.	It comes with a set of built-in commands. If a command is unknown, the command will shell-out and execute it (using cmd on Windows or bash on Linux and MacOS), correctly passing through stdin, stdout and stderr, so things like your daily git workflows and even vim will work just fine.
Command line editing; Unlimited size command history; Job Control; Shell Functions and Aliases; Indexed arrays of unlimited size; Integer arithmetic in any base from two to sixty-four	Cross-platform;Ensures direct compatibility with existing platform-specific executables ; Views data as both structured and unstructured; An object shell like PowerShell

What are some alternatives to GNU Bash, Nu Shell?

JavaScript

JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.

Python

Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.

PHP

Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.

Ruby

Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

Java

Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!

Golang

Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.

HTML5

HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.

C#

C# (pronounced "See Sharp") is a simple, modern, object-oriented, and type-safe programming language. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers.

Scala

Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.

Elixir

Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.
