May 5, 2020Love your Tutorials very educational and easy to comprehend good teacher. Can you make a tutorial on bash scripting? Thanks

May 5, 2020So simple yet so full of possibilities. Great vid! Seriously, I know there is 'man echo', but the layout is not intuitive to learning–and that's with all the 'man xxx' commands. Until you see it in action as you demonstrated its usage escapes me.

May 5, 2020Hi, Can you please make a tutorial on how to use hybrid GPUs on Arch Linux, i have intel and nvidia and i want to be able to switch between them, intel is very good for battery but terrible at games, Nvidia is good but i can't unplug the laptop charger without it shutting down in 5min. i priviously could switch on Ubuntu, i tried installing nvidia-390xx-lts but it doesn't let me (breaks dependecies), internet said that it was due to kernel, i installed linux-lts (using your tutorial) but now i cant uninstall (linux) because it breaks dependency 😕

May 5, 2020Was really surprised to see a 10 min video about "echo" as it's a very simple command.
Pretty much 90% of the features demonstrated are bash features and not "echo" specific. Bash handles arithmetic expansion, brace expansion, special characters, etc. Therefore all of this is true for "printf" as well.

May 5, 2020Hello ALU! Oops, {} are not brackets but curly braces! There are a few typos in your file echo.txt There is Arithmentic instead of Arithmetic Expansion Under #Quotes second line there is manu instead of many and under #Escaping characters it should be costs instead of cost
Cheers

May 5, 2020Nice examples! 'echo' is a very cool command but, to some extent it is very unintuitive. At 9:27, I did not understand the command 'echo line 1$'n'line 2' at all?! Why all of a sudden single quotes, and not double quotes? With regard to the arithmetic operations, we want an expression like $((2 + 2)) to be interpreted within double quotes but, not within single quotes! So why is it that $'n' is interpreted as a newline but $"n" as n? Also, how shall the user know that 'echo line1$'n'line 2' yields the same as 'echo -e 'line 1nline2' '? In my opinion these kind of peculiarities should be documented in the manual page. But, unfortunately, 'man echo' does not provide more information than 'help echo'.
