Ok, thank you SO much. I bought a course on Udemy and I didn't like how there were pre-made files and when they ran commands for those files, I wasn't able to follow again.

Now on here, the BEST THING you did was made files so that the viewers followed along. I thank you so much for this.

GUI definitely turns your brain's into goo. Thanks for this, I'm much more confident having a bash on terminal.

In chmod section, byte is 8 bits as it is 0 to 7. You said it right right after explaining in example. Thank you so much for making such a great video to help me understand Bash 🙂

Less shows you more, and more shows you less… I can see the logic in who ever thought this.

Example of command in sentence:
When you need more of this, use less 😑

sorry i'm a bit confused because i wasn't focused. i am just starting out as an intermediate because i know a few commands in linux and i felt a bit over the place when you mentioned all the basic commands. i know it's not good for everyone but i want to learn the basic concepts about these commands not just how they work, even if i have the tools to run these commands in my terminal i won't understand them unless i learn how they work or what other things they can do when used in command line. aside from all of this, i want to say i like your videos and some of them really helped me a lot when learning. i just had trouble finding the right resources to stay on focus and get the right commands to use my terminal properly. my suggestion though is perhaps next time you could add a list of helpful links in the description so some people like me can navigate links much faster and get helpful knowledge. Thanks!
