Unix forms a foundation that is often very helpful for accomplishing other goals you might have for you and your computer, whether that goal is running a business, writing a book, curing disease, or creating the next great app. The means to these goals are sometimes carried out by writing software. Software can’t be mined out of the ground, nor can software seeds be planted in spring to harvest by autumn. Software isn’t produced in factories on an assembly line. Software is a hand-made, often bespoke good. If a software developer is an artisan, then Unix is their workbench. Unix provides an essential and simple set of tools in a distraction-free environment. Even if you’re not a software developer learning Unix can open you up to new methods of thinking and novel ways to scale your ideas. This course is intended for folks who are new to programming and new to Unix-like operating systems like macOS and Linux distributions like Ubuntu. Most of the technologies discussed in this course will be accessed via a command line interface. Command line interfaces can seem alien at first, so this course attempts to draw parallels between using the command line and actions that you would normally take while using your mouse and keyboard. You’ll also learn how to write little pieces of software in a programming language called Bash, which allows you to connect together the tools we’ll discuss. My hope is that by the end of this course you be able to use different Unix tools as if they’re interconnecting Lego bricks....

A wonderful course! Answered so many questions I had and gave me a solid background in Git, Bash, makefiles, and working from the cloud. I will definitely be using these skills in my job search!

It is suitable for Unix/Linux beginners who are new to shell. It introduces popular code sharing and merging tool GitHub, which most programmers would find very useful in software development.

Excellent introduction to the command line and github. Great as it goes past superificial introductions and teaches programming and manipulation of the command line.

Lazy, Sloppy, Unfocused

Lets see

-Video content is minimal. This is not really a video course. I've never experienced this on Coursera before, the 4 videos that do exist aren't useful in any way.

-The is some introductory, and unnecessary, introduction to both cloud computing and ssh / scp commands. I'm not really sure why it's there, when all of the assignments focus on both git and bash. So anything you did learn in these sections (likely nothing) isn't reinforced. It should be bonus material.

-Many things about bash are truly unusual compared to other programming languages like python/r/php/etc. When these differences crop up (such as how bash handles (), {}, [], [[ ]], spaces, AND, ||, functional returns, etc) are still somewhat confusing to me after completing the entire course. So maybe I'm a dummy, but I'm guessing MOST people completing this course will only be slightly better off doing bash programming vs. doing nothing at all.

-Quizzes were often trivially easy. What will a bash command output? Well, I guess you're not *supposed* to just run the command in bash to see the output...

I could go on, but honestly, this is a terrible course. I actually need to use bash at work, having a certificate is nice I guess, but my time may have been better served with trial and error on my actual projects.

Very good overall, I will give it 5 starts!!!

But small advice, since it is written in markdown, I hope we can use code blocks to make the keywords like unix command stand out which can help us easier to find it and give more clear context structure.

Good and well-paced course. I'd like to see more Unix and less clouds.
