Moore's Law of computing is very debatable nowadays, but one tech-related concept that's absolutely NOT debatable is that everyone learning any scripting or programming language should start with the classic "Hello World" example. And you know what? LearnLinuxTV is a sucker for tradition. So in this episode, you'll write your very own Hello World script in Bash!

This is a terrific video. I have been trying to find a good resource for quite a few days now. They go on and on about all the commands used. But none showed how to execute a file in the very beginning. By doing so, you have made me realize the scope of bash scripting in the most efficient way. Thank you.

@AyalaStudios 3 месяца назад

Hey Jay! I started watching your videos this past month and I can see the progress you've made from the uploads 4 years ago to the uploads today! Your way of explaining topics seems to have always been awesome - but your camera presence has definitely improved over the years! I just want to thank you for creating the content and show my appreciation. Your instruction is the the kind that many people can benefit from and I hope you continue to create amazing content!

Thank you, Jay. This is super useful. Kinda genius to put the entire thing online at the same time too. Perfect chunks for a person like me. Thanks again.

I've just learned basic bash scripting and I can see this getting addictive. As soon as I do something in multiple commands I immediately think of building a script or .src function. First is mkcd to make and go into a directory. Then mkpyapp [packages] to make the common app structure I use, create a venv and install the rest of the arguments as packages in that venv. Finally open up folder in VS code. Then actscript to put bash script in ~/bin and make executable. Any many more in the pipeline... It's so much fun! Look forward to learning more here

Hi jay . Thank you for vim training and I learn a lot . Now starting script training and thank for all your time and training. Mr. Jay I am not sure why you use nano for training script. I was expecting to use vim. I am sure you know better or may be nano is better to writ script. Thank you again.

Is it just me? I always put 'exit 0' at the end of my scripts. Even if I don't have other exit values else where in the script.

What about POSIX compliance? Wouldn't it be better to go that route instead for compatibility? That being the case, why not code for dash instead of bash? The resulting script should be executable in dash, bash and zsh (with compatibility mode).

8:40 - hi! I've got two questions. 1. What for did you add "./" in front of a script name? 2. Why didn't the script show objects' names in colors. If it does the same as the command ls, then the result should be the same I suppose.

8:48 I'm curious why when it showed the contents of the directory it doesn't color the folders and such like it did when you just typed ls? Not nearly as useful as a script.

If there's no sense in .sh extension, how does Linux know that it is a bash script? For example, in html we have a header line. But here there's no header. What if a file is in ZSH but has an .sh (bash) extension?

@tatsutakamaro 8 дней назад

Already saw it. She bangs, okay.

@luciengrondin5802 Год назад

There is no need to search for bash with `which` in order to execute it. In case your default shell is not bash, and assuming bash is installed, it should be in the PATH so you can just type `bash`, or even `exec bash` to replace the current shell.
