Initially, I had found this video by accident. Subsequently, I lost it. Today, I remembered the general subject matter Linux Bash and found it yet again. This is very direct and to the point. On a scale of one to five stars, it rates five stars !!!

You do an *excellent* job at simply showing what the commands do and then letting students look into the commands further. Most teachers, especially in college, tend to give far too much exposition when explaining simple concepts. While knowing about GNU is important, you certainly don't need to know where Linux came from to understand and execute a command like "pwd". Thank you for doing a great job with your teaching.

[Airisweetheart]

This guide is excellent I have been through several Linux bash tutorials and they would explain the simple command but with zero context. You give great context and great examples. Thank you so very much for this guide! Excellent work. 10/10.

[miserableoldbastard]

I just found this and Lane is a awesome teacher I'm going through these lessons. I am new to Linux and he really makes things clear. thank you

[mr.thursday]

(No Sarcasml seriously) Your voice is refreshing after all the tutorials I've watched. Easiest 3hrs of my life

[kanishkapillai]

[JohnBrodt]

Dude you make the best teaching linux ever!!! Fast and to the point, nobody beats that anywhere. Thank you for saving me so much study time!!! What I learn from your teaching style is 10x faster then any youtuber!!! You really do rock!

[salsafever]

Thanks to Lane Schwartz for a perfectly scripted lesson and equally perfect audiovisual delivery, and thanks to the Geek's Lesson Channel for making these lessons available for free. You speak to the very essence of humanity.

[subrataray]

Awsome content . That too in free. Don't feel like skipping the add. You deserve it. Everyone please don't skip the add

[OreWaKitasu]

OMG The understanding complex relative paths parts ALMOST killed me of boredom. And I fast forwarded, mind you! This is one of the most unnecessarily long explanation I have seen in all my years in tech!

[gabrielafialova]

Thank you very much for this course, it did me a great service. I like your teaching methods and the way you take the time to break down and explain all examples in details. This helped me a ton!
