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.
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.
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 :)
there is nothing called as boomer...there are just smart people who continue to learn and improve throughout their lives being a valuable member of society and inspire others...you seems to be of that kind

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.
[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).
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.
"Laugh at it" 100 times! No need to laugh at people you can politely correct them and explain to them so they understand.

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).
You can kill a process in any language - here is an example for C: stackoverflow.com/questions/6501522/how-to-kill-a-child-process-by-the-parent-process
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!
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.
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.
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.
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 ;) Edit: typo
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.
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.
Running Python as your primary shell isn't really such a crazy thing, actually. Well, the normal built in python shell is not really suitable as a command shell, but there are alternate shells like xonsh which are designed to replace bash in interactive use by mixing together python and bash syntax, so you can do things like piping and redirection, but also use python syntax for things like writing lists, dicts, loops, conditional statements, functions, classes, etc which is much simpler than bash's syntaxes. Another possibility is to use IPython with full rehashx magic, which will load everything in your $PATH into IPython magic commands, so you can run any system commands just like in bash. IPython used to even ship with `sh` profile which is designed for use in this manner.
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.
Wants to make everything clear. Starts directly by saying "this window is a terminal emulator and it is also running a shell, like bash". Seriously dude? Is that how you start explaining what bash and a terminal is?
What about cmd and powershell? A lot of people would know them way more than bash cuz they use Windows. Are they languages too? Shells? Terminal emulators? Sad that this explanation didn't include those
This code for color profile is similar to Luke's PS1="\[\033[01;31m\][\[\033[01;33m\]\u\[\033[01;32m\]@\[\033[01;34m\]\h:\[\033[01;35m\]\w\\[\033[01;31m\]]\[\033[01;37m\]$ " It will work in most terminals that have default settings and without any addons. Luke, thank you - great work and inspiring.
10:26 "[terminals] can run lots of different things that are not command prompts" Does vim (or TUIs in general) fall within this category of non-shell things that can run within a terminal?
Terminal has roots in a mainframe world. It used to be a screen with a keyboard and connection to a mainframe. You had an editor that basically allowed you to write and run programs. Before terminals, you had punch card reader. Each card was a line of code.😅 Bash was used on terminals.
Personally, I don't see why a normal user's prompt on a local machine should have the user@hostname section. Obviously it should always be clear if you are root or on an ssh connection, but it seems like a huge waste of space. I have my Zsh prompt set to: [0]:~ % %F{green}[%F{yellow}%?%F{green}]%f:%F{blue}%B%2~%b%f %# %# will be % or # depending on if you are root, but I have kept Bash as the shell for my root user just to make it really obvious.
03:08 how do I copy and paste in bash? no I do mean it, how do I make my bash script put things in my clipboard? can I choose which clipboard it will use? that's not obvious and tricky making it not as dumb as it seems 🤔
How about this: ""I opened my terminal, which was configured to run the shell program Bash. My cursor was blinking at the command line. My prompt was showing the current directory.""
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
5:03 That's not true. The Windows 11 terminal allows users to utilize Ctrl+C for two functions: copying when something is highlighted, and terminating when nothing is selected.
3:53 so, command prompt is same as terminal emulator? 10:29 amh no. i still dont get what a command prompt is. i get what prompt is, and what command line is, but what is command prompt?
I've seen AHK scripts that run to hijack the Ctrl+C and ask whether you mean to copy or break so that people with the Windows muscle memory aren't constantly causing fits when using SSH - seems like a clunky workaround but it saves a lot fo time for the people who only sometimes ssh into Linux and don't full-time
I think Shell is an Interpreter, that can interact directly with the OS. Whereas Sh, Bash, Zsh, Powershell are differerent kinds of Shells (or Interpreters) Correct me if I am wrong

How do I copy and paste in bash

It will work in most terminals that have default settings and without any addons.
Luke, thank you - great work and inspiring.
So what is the difference between a command line (interface) and a terminal emulator?
So terminal is the window, bash is the language inside the window, command line run different languages, and prompt is a specific name in each shell?
3:13 there is no such thing as a dumb question

[0]:~ %
%F{green}[%F{yellow}%?%F{green}]%f:%F{blue}%B%2~%b%f %#
%# will be % or # depending on if you are root, but I have kept Bash as the shell for my root user just to make it really obvious.
"You secretly have something to learn you don't know about" got me :_D
afaik bin/sh is just a symlink to bin/bash on some distros to not break some program/script
To be fair, “how do I copy and paste in bash,” might be asking about piping the output of a command to the clipboard, so it’s not entirely stupid.
03:08 how do I copy and paste in bash?
no I do mean it, how do I make my bash script put things in my clipboard? can I choose which clipboard it will use?

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?
actually, BASH, zsh, cshell, et al are command interpreters, correct. Like DCL is the command interpreter for VMS and RSTS.
How about this: ""I opened my terminal, which was configured to run the shell program Bash. My cursor was blinking at the command line. My prompt was showing the current directory.""
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
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.
In the old Unix days a terminal was a end point to have access to the mainframe.
5:03 That's not true. The Windows 11 terminal allows users to utilize Ctrl+C for two functions: copying when something is highlighted, and terminating when nothing is selected.
Okay but on windows PowerShell is both a language and a program that pops up a window for text input
3:53 so, command prompt is same as terminal emulator?
10:29 amh no. i still dont get what a command prompt is. i get what prompt is, and what command line is, but what is command prompt?
I've seen AHK scripts that run to hijack the Ctrl+C and ask whether you mean to copy or break so that people with the Windows muscle memory aren't constantly causing fits when using SSH - seems like a clunky workaround but it saves a lot fo time for the people who only sometimes ssh into Linux and don't full-time
I think Shell is an Interpreter, that can interact directly with the OS.
Whereas Sh, Bash, Zsh, Powershell are differerent kinds of Shells (or Interpreters)
Correct me if I am wrong
This is exactly what i needed thank you
