So, to sum up:
- Terminal: Program that emulates the functionality of an old terminal. Nowadays it includes much more functionalities than old days.
- Bash: Interpreted language than is being used to interface with the computer and OS.
- Command line: The line in wich you are writting the code inside the terminal
- Prompt: Small portion of information, at the beginning of every command line that shows something related to the computer user or basic information about the computer within few words
Let me know if i am wrong. Dont forget, we all are learners, dont take it seriusly.
Thank you!

I've lived all of 67 years now and it wasn't until I began watching you, Luke, that I learned I'm a boomer and that I have all these amazing powers at my disposal. Who says you can't teach an old dog new tricks? Bah! Humbug! From one boomer to another, I love your vids :)
ok boomer

2:07 Sure, you could consider bash a language. But the terminal emulator isn't running bash-the-language, it's running bash-the-shell which runs bash-the-language. (A shell is a type of interpreter.) Also, the shell you use is normally decided by a per-user configuration setting, not by the terminal emulator.
Thank you for this clarification.
This is useful, Thank you!

I have never seen this type of video before, but it is suddenly obvious that there should be more people pointing out these differences. Very good! Thank you.
This is SOOOOOOOO desperately needed! You made so many nice tutorials before but if this one is not cleared out of the way those tutorials could not be appreciated by newbies. Thank you so much my Tech God Luke!
love your explanations on stuff... always clear, concise, and complete...

Angry command line
"bash is merely a language" "bash has this binding control C"
"Laugh at it" 100 times! No need to laugh at people you can politely correct them and explain to them so they understand. Noobs are in a learning process and the last thing they want is to be launched at. Keep doing the good work through your videos and be more sensitive towards noobs because this is a field where even the most experienced engineers have new technologies to learn almost every year. By the way I gave the video 👍🏽
You are very talented in explaining complex stuff. Thank you so much and keep posting videos plz.
[9:40] Sure, the prompt colors are set in the shell configuration, but they're not interpreted by the shell. It's the terminal emulator that interprets and displays them (ANSI escape codes).
They usually are in the form of prompt formatting strings like "%cb". Then the shell will emit the escape codes that your terminal supports (as written in the termcap files).
@@Mankepanke I *hope* the shell uses Terminfo and not Termcap. 🤔
@@humm535 isn't terminfo the API that read the the termcap files?
"What is bash?"
Isn't it obvious? Bash is bloat.
3:08 CTRL+K, CTRL+U, CTRL+Y is basically -copying- cutting and pasting in bash.
Copying/pasting to/from clipboard in a script could fall under "copying and pasting in bash" too.
Hey, Luke! There is a way to run Python-like environment as a shell. It is called xonsh and it is a superset of Python aimed to make it more shell-like (completion, piping, history, easy access to environment variables). As far as I know it is in development but that's pretty cool project (but to be frank it has many issues, e.g. slow startup time).
Another awesome and informative video! Thanks Luke!
I did need this video. You answered questions I've been wondering about.
This is the video I was looking for, but I didn't know it until I watched it. Thanks!
I truly love your stuff Luke.
Great content. Keep up the good work Luke!
3:04 Rather than “stupid question” I’d call it an ambiguous question. As such, it is one that is NOT likely to be answered the way the asker intended. Asking how to copy/paste in bash could mean to read/write the OS clipboard, it could mean yank/put in `set -o vi` mode, it could mean to pipe into and out of `tee`, it could mean to `exec > >(tee $name.log | log -t $name)`, etc. Great info though.
Yea what about the cp command as well
Love it, when Luke's face appears in the beginning, i know it's gonna be goood. :)
This is a well done introduction video thanks a lot!
Good video!
I'd also add in about a little difference between CLI (ls, dd, youtube-dl, pacman) and TUI (vim, newsboat, ranger, irssi) programs while on this topic, because people tend to confuse these pretty often.
thanks for it, yep, i had idea tthat those are different things, but didnt know the exact names. thanks for sharing
@@yash1152 no problem!
I'll elaborate on the distinction a bit. As a rule of thumb, CLI software is easily scriptable, while TUI is more interactive and keyboard driven.
If it's output can be effectively parsed using grep, it's CLI. If it has GUI-like rich interface, but on the console (usually by means of (n)curses library), it's TUI
@@netrezv thanks a lot for input.
> _"ususally by means of (n)curses library"_
yeah, i have read that curses/ncurses thing on web: "vim in ncurses based editor" but on trying to look it up surfacially, it went over my brain.
> _"CLI = scriptable; TUI = Interactive + keyb driven"_
so, TUI can still have some daily use applications like ViM editor, ViEB browser, etc. But the scope of CLI is very different than normal applications right? i mean, yeah, it's fast for batch, piping, and specific actions etc, but still, those are not the things of normal daily use. am i right?
What is TUI short for? Text User Interface?
5 years of being a Python coder, and never knew how much I needed this video
I have two questions:
1. How do I copy and paste in bash?
2. How do I scroll up and down in bash?
Joking aside, I'm a complete newbie and those are the questions I would have definitely asked before having watched this video. I can now confidently say that the amount of silly questions I'll be asking in the future has decreased by two. 😀Thank you.
Still have more silly questions?

Quick Summary: Terminal, Bash, Comand Line, Prompt... different aspects of what you may be using at the same time.
[1]: a TERMinal started out as the *Hardware* keyboard+display on your desk (with NO processing logic inside) that sent all keystrokes to a remote computer (where the thinking+CPU+programs run) and the computer would send text information back to be displayed for you. Like THIS VT100 terminal: en.wikipedia.org/wiki/VT100 For the last 30 years, this is usually a terminal *emulator* program that behaves the same way that an old terminal Used to... but no separate hardware.
[2] BASH is a "shell" program that runs as soon as you login to unix/Linux, and tries to understand commands that you type, then figure out what you want the computer to do next. (often by finding another program you want to run) There are sever "shell" options: sh=Bourne-Shell, ksh=Korn-sheell, csh=C-shell, bash=bourne-again-shell, and more.
[3] a COMMMAND Line represents the command/directions/request/instructions that YOU type into the computer's shell.
[4] a PROMPT means that the computer is waiting for you to type something in to the computer from the keyboard. Prompt also refers to any short text message that the computer prints out (just before the cursor) to let you know what's going on, and what to type next.
So... al lof these may be "active" at the same time when you are logged into a Linux computer.
The terminal could be the "window frame" and background, that defines the frame, appearance, fonts, and general "canvas" for text information to be displayed on. Within that terminal environment, the computer may be running a bash "shell" that is displaying a prompt, and waiting for you to type a command line. After you type the command line and press enter, the shell reads that command line and tries to do what you want, or finds another program that will do that for you.
If you want to change how things LOOK, for background/fonts, or scroll around, that is generally related to the Termianal's scope of responsibility.
If you want to change how things BEHAVE, or your environment variables, or change your prompt, work with the Shell.
If you want to automate things with a simple "shell script" program, then you will need to create a file full of shell commands using an editor like vi/vim and then tell the shell to run the commands in that file.
Almost anything else requires running additional programs. (which the shell will help you find+run through $PATH directories)
SO: That's a 30 second summary of this 11 minute video.
So, tell me Luke.

Hey there, love you're stuff. Just a small observation: Running /bin/sh happens alot when you are working in container land so POSIX compliancy has risen at least in my scripts ;)

Hi, very indulging video and thanks for identifying these major differences.
In short all of these different things are different.
This video was very helpful! Thank you!
Love your content. Big vim help when I was new to it.
finally understanding some basic things,thanks to you, it was great help
OH YES NEW VIDEO !!! Thx luke i learn a lot with you !
5:12 Hold on: if bash is a language, how can it have a setting to stop a running program? Were you referring to the bash interpreter perhaps?
You can kill a process in any language - here is an example for C:

Actually...THANK you! I always wanted to change the prompt color schemes 🙏
It's also good to know about interactive vs non-interactive shells and login vs non-login shells
Wow great explanation Luke!
SO SO helpful thank you !!
Thanks man, not the target audience, but this helped me a lot. I just opened up a terminal for the first time in my life to copy/paste and patch a game on Linux. Really just wanted to know some basic terminology to research further and understand what exactly I was doing.
Hi, I loved this video. where can I find more information on how the shell interprets and execute commands? Specially the interface with the kernel.
thanks, i am a 15 year running (open)SUSE amateur...this video clears up a bit of the "pro mind set"...Thanks for the effort (Y)
Then what does it mean to run shell on emacs (M-x shell)? I'm really new to this and learning kind of randomly, so forgive me if this is a dumb question
Thanks for the Information Dr.Eggman
Helpful a bit like parameter, argument and keyword arguments
How do u increase font size of the terminal?
depends on the terminal

Thank god for this video. I’m taking an operating systems class and was confuse during lecture. 😂
Hey Luke, how do I change font size in bash????

Me thinking the last video was good.
Luke: there is another
EDIT: just realized that this comment was cringy as hell.
Thank you for this video. This is the answer to the questions I have.
Very informative video, learnt something good about shell promps today :) nice
Are there any interactive shells available for javascript as well? Which one are you using? Whats so nice about it?
Thanks in advance
Thanks for informative video!!
I am confused about the stdin and stdout I was able to let’s say open 2 terminal windows in zsh (or bash etc) and (but I don’t remember how) run a command, like echo something > to/a/destination and it was echoing in the second terminal window... I am looking to get my understanding right about what is the difference between stdin/out vs. the name of each output and I am as much confused as those people mixing the prompt with terminal with bash... etc
This is exactly what i needed thank you
Epic battle!
Like :)
Thank you, fun video to watch.
I have a love/hate relationship with BASH...
It is extremly powerfull but sometimes it drives me nuts..

guys cmder find many problems in the windows. Is there a solution or is there a better one?
Thanks Luke. My confusion is being directed better now.
boomer uses zoomer shell 😱
I was really confused with the word like bash, shell, terminal emulator and other.... Thanks to you I get the point
Thank you for this.
your video dint solve my question that is what the diference between prompt and terminal, i tryed to run a command ssh root@domain and he dint reconize the command ssh
Thank you for this information Sir
Nice, very helpful.
> Ctrl-C will not work in any kind of terminal emulator to copy things
conhost.exe (cmd) does just this, and it's better too. Why would you want to stop your program when in visual mode?
So what is the difference between a command line (interface) and a terminal emulator?
This is a very good video .. good to know these terms
How do I copy/paste in bash?
What I could have meant: I have a File, that I want to Copy using a bash command. How Can I do that?
"You secretly have something to learn you don't know about" got me :_D
You do not have to laugh at people not knowing things, but at least you gave them a chance to know it. Appreciate it
The terminal on tinycore has this behaviour, which I think comes from flwm, the window manager: highlight something with a right click to copy, then middle click to paste. That's really annoying. The mac terminal has probably the most intuitive copy-paste behavior because macs use the command key for keyboard shortcuts, so the terminal can just use the regular shortcuts.
Bash, zsh, the shell I would say , should be defined as "your environment" and the command line being "your non graphical interface"

How do I scroll up and down in Bash? xD
So the terminal that I open on my Linux is an emulator ?
Thank you!
Hi Luke, any updates on Latin books project?
From where I can get your terminal emulator?
are window powershell and cmd considered as terminal emulator or shell?
Thanks!
Tinycore linux uses /bin/sh as the default shell. It uses busybox, I believe, which gives a POSIX-compliant, but not bash-compatible shell, which has caused me headaches when running scripts that assume that /bin/sh is bash.
Another stupid question. How do I copy some text from above command line into command line? Let's say, I ran some program, it outputted some text, I want to copy part of that text and put as an argument to another program or something.
Nevermind, apparently, you can't, unless you're using Luke's build of ST.
I would say your terminal (emulator) decides which colors etc. you can use how in your PS1. Or is your zsh directly talking to your graphics chip?
