The course covers a lot of ground in just two modules. I liked how it built from I/O and file streams into real-world system administration. The security enforcement and user management sections were very relevant. My only wish is that there were some bonus labs for advanced practice.

A solid introduction to both the practical and conceptual side of Unix. I came in with very little knowledge of I/O streams, and now I feel confident working with redirection and text substitution. My only suggestion is to add more real-world case studies on user account management.

The course not only showed me how to use commands but also explained why Unix handles I/O the way it does. That gave me a much deeper understanding. If I had to critique something, it would be that the examples on device mounting could have been expanded with more scenarios.

This course gave me a much clearer understanding of Unix input/output handling. The use of sed and regular expressions was explained in a way that finally made sense. I think Module 1 could use a few more hands-on exercises, but overall it’s very practical.

This was a very comprehensive course. I especially liked the part on system components and abstraction—it gave me a new way of looking at how Unix works. That said, a few extra practice exercises on text substitution would have been nice.

What stood out to me was how well the course explained standard redirection and file operations. I now use these daily in my scripts. Some of the disk management parts were a bit dense, but overall the course gave me a solid foundation.

As someone who already knew the basics of Unix, I found this course very refreshing. It focused less on theory and more on doing. My only minor complaint is that I wanted more advanced case studies on data processing with awk.

I really appreciated the balance of theory and practice in this course. Navigation and permissions was especially useful for me as a beginner system admin.

One of the clearest treatments of expression handling I’ve seen — the walkthroughs of parsing logic made tricky concepts accessible.

The modules are structured well, starting with I/O basics and then moving into system administration tasks. I especially liked the section on disk management and permissions. Some parts on regular expressions felt a little fast-paced, but rewatching them helped.
