Reviews summary

Understanding linux command line

learners say this series of around 50 short videos provides a largely positive learning experience for beginners who want to learn the basics of working with the command line in Linux operating systems. The course is paced to allow the new user to digest the material while providing ample and engaging examples. Some experience with Linux is helpful but not required. There are five main sections in the series, beginning with an introduction to basic file and system navigation and ending with working with aliases and wildcards. Each section begins with a brief introduction to the topics that will be covered. At the end of each video, the instructor reviews the main points and provides an overall summary of the material covered. Tests at the end of each section help users reinforce their learning. The contributors largely agree that the instructor's presentation style is effective. They found him to be engaging and knowledgeable and appreciated his frequent summarizing of material. However, some more experienced users found the pace of the course to be somewhat slow and repetitive. They also wished that there had been more coverage of some topics, such as working with permissions and using shell scripts. Overall, reviewers appreciated the large number of practical exercises and the extensive use of visual aids, such as screen captures, diagrams, and animations.

The course is paced well and provides a good level of detail. The instructor does a good job of explaining the concepts in a way that is easy to understand, and he provides plenty of examples to illustrate the concepts being taught.

"The flow of the lectures is slow but not boring, which makes it easy to understand."

"Thank you very much for this amazing course. This course is helpful for beginners and intermediates but not very helpful for advanced Linux users as a few more things could be added like IP commands, change file permission commands, user permission commands, etc."

"This course was a great introduction to Linux and I benefited from it."

The course makes extensive use of visual aids, such as screen captures, diagrams, and animations. This helps learners to visualize the concepts being taught and to better understand how to use the commands.

"I really appreciate that you know how to provide the best way to learn through your videos."

"Great first course for beginner or if you've been away for a while. Inclusion of an overview of the 'find' command would be helpful."

"Been working in linux (learning) for 9 months now and this is the easiest for me to understand because of the visual learning component!"

"Visualizing is one of the hardest parts of switching from GUI to command line."

The course includes a large number of practical exercises. This helps learners to reinforce their learning and to gain hands-on experience using the commands.

"This is great for me because I need lots of repetition for things to stick when learning new things."

"The instructor was intuitive to me, at least, as he taught and would consider showing another example which I had hoped would be presented."

"As a DevOps engineer for sure, you need to know these, and I was expecting a bit more advance."

learners say the instructor does a great job of presenting the material in a clear and engaging way. He is knowledgeable about the subject matter and provides plenty of examples to illustrate the concepts being taught.

"The course is well thought out, funny at times (enough to break things up when necessary), and easy to follow along."

"Ahmed is fantastic instructor and keeps it simple and has broken up the material perfectly!"

"The instructor is very experienced, he explains each command with examples, and many possible options."

"Explanations are very thorough with an emphasis on the just-learned concepts which helps in solidifying comprehension."

Some more experienced users found the pace of the course to be somewhat slow and repetitive.

"It moves quickly without bogging you down. You get a good overview of the command-line in Linux."

"I gave a four-start rating because everything that was presented came in easy-to-remember sections."

"I think that it would have been better if he teaches some advanced commands such as grep, chmod, chown, pipe, etc."

Some more experienced users wished that there had been more coverage of some topics, such as working with permissions and using shell scripts.

"I had already learned some of the commands covered so far, I think it was a very good decision for me to start from the beginning just to get the complete picture in the right way instead of what I did so far: learn by trial and error and see what happens...."

"This course explains basics of linux basic command lines. Those who are familiar with the basics command, this course will add on something new to this which we generally don't know."

"Excellent course for beginner Linux users! By the end of this course you will know how to get around the terminal and will know how to use many very useful commands."
