Generally mediocre introduction to a few bits and pieces of unix. Useful, but has some misconceptions (e.g., what a regular expression is) and will teach you some unsafe habits (e.g., using $* instead of $@ to expand to the positional parameters starting from 1). It would be nice if there was some discussion about what shell scripts were actually used for out in the world. The cloud computing section seems tacked on and wholly unhelpful. Don't make your students give their credit card numbers to some external business unless you're going to do something of at least some lasting value. Even then, you probably should find another way to do this. Set something up on a coursera or JHU server if all you're going to do is literally have them copy and paste (and not learn) 6 lines of code.

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.

This is a good course, barely adapted from Sean Kross' UNIX workbench book. Much of the course material refers to chapter numbers but is easy enough to follow without the book. I found that some sections did make a few leaps between the written content and the exercises. For the most part this was OK but the exercises for the final section, "Nephology", were well beyond the written content ("now make a Twitter bot"). Also, the course required that we sign up to Digital Oceans (and gave us a credit)...be prepared for spam and officious disregard for customers.

Tremendously useful course.

Course is easy and straightforward, no excessive effort is needed to complete it.

amazing course

Really useful course for learning the basics of Unix

Excellent material!!!! More practical exercises please will do...

Excellent! Peer review was a great first experience, but very worthwhile to look at other's work after thinking hard about the problem myself. Very well structured - and I now feel confident on cloud computers, bash, and UNIX/GitHub.

The course was really interactive. It was a fun experience.

Would have been better if you had provided the learning experience in visual form rather readable.

Anyways Kudos!

Great content and excellent exercises.

I really want to learn Unix and Git for a long time but I was struggled with finding a good resource to learn. Thanks to Coursera and John Hopkins University, this course gives me what i really expect to

Material was great. However, last assignment instructions were not clear.

Very well done course. One of the best ones I did.

Nice overview of the important UNIX (Shell) programming fundamentals.

Overall, the course was well structured and easy to understand. The mentors reply regularly to any questions posted in the discussion forums. A wonderful learning experience that introduces you to the command-line interface.

Great introduction to the shell world to start swimming on your own!

I chose to take this course as reading manuals is boring. The course is nice in the sense that it gives practicals that you can do and get yourself familiar with the commands. On the other side, the videos are not what I expected and not so useful to have anyways.

Best course for basic unix knowledge

good add more content

I've been searching for good introductory courses into Unix for over a year now - and finally, I found something with the right amount of challenge and pace that could be achieved within a month's time. Thank you to Sean Kross and the team that developed this course! I'll be paying attention to this space and I now feel I have a better foundational understanding of the ethos behind Unix workflows...

Well presented short course easy read content

You need videos, not enough and all reading here, although it was the easiest course I've even started and completed. Took less than 1 day to complete and pass.

Very nice course for linux beginner.

excellent topic for beginer
