Episode Overview

In this episode, Herman and Corn dive into the fascinating world of Command Line Interfaces (CLIs) and why they are seeing a massive resurgence in 2026. They trace the history of the terminal from 1950s punch cards to modern GPU-accelerated emulators, exploring how the "Unix Philosophy" of simple, composable tools is more relevant than ever. The duo discusses why AI agents are moving back into the terminal and why the command line is actually a higher-resolution interface for the human mind.

In a world dominated by touchscreens and sleek graphical user interfaces, a sixty-year-old technology is making a surprising and powerful comeback. In the latest episode of My Weird Prompts, hosts Herman and Corn Poppleberry explore the enduring legacy and modern-day resurgence of the Command Line Interface (CLI). What was once seen as a relic of the 1980s hacker aesthetic is now being hailed as the "cockpit" of the modern developer, especially as artificial intelligence begins to take a more active role in software engineering.

The Deep Roots of the Terminal

The discussion begins with a journey back to the dawn of interactive computing. Herman explains that before the windows and icons we use today, computing was a slow, physical process involving punch cards. It wasn't until the mid-1960s, with projects like MIT’s Project MAC and the Multics operating system, that the concept of a "shell" emerged. This allowed users to interact with a computer’s kernel through a protective outer layer of text.

The "Big Bang" moment for the terminal arrived in the early 1970s at Bell Labs, where Ken Thompson and Dennis Ritchie created Unix. This era birthed the Bourne shell, the direct ancestor of the Bash shell used by millions today. Herman highlights that the longevity of this technology—nearly sixty years—is almost unheard of in the fast-paced world of tech.

The Unix Philosophy: Power in Simplicity

A central theme of the episode is the "Unix Philosophy," a design principle that suggests each program should do one thing and do it well. The brilliance of the CLI lies in "pipes"—the ability to take the output of one simple tool and feed it as input into another.

Herman uses the metaphor of Lego bricks to describe this workflow. While a Graphical User Interface (GUI) limits a user to the buttons and menus provided by a developer, a CLI allows the user to be the architect. By combining small, specialized tools, a developer can build a custom solution for a complex problem on the fly. This composability is why the terminal remains a "power tool" rather than a nostalgic novelty.

Why AI is Moving Back to the Terminal

One of the most intriguing insights from the episode is the intersection of the command line and modern AI. Herman and Corn discuss why state-of-the-art AI tools, such as Claude Code, are being integrated directly into the terminal rather than living in a web browser.

The reason, they argue, is twofold: context and friction. For a developer, the terminal is where the work happens—where code is edited, compiled, and deployed. By placing an AI agent inside the terminal, the AI gains "eyes" on the environment. It can see compiler errors, navigate the file system, and even execute commands. This minimizes "context switching," allowing the developer to stay in a state of flow while the AI handles the heavy lifting of execution and debugging.

The Rise of TUIs and High-Performance Tools

The conversation also touches on Terminal User Interfaces (TUIs). Unlike the strictly line-by-line CLI, a TUI uses the entire terminal window to create a visual layout using text characters. Herman points to modern tools like Yazi, a file manager written in Rust, as examples of a new wave of high-performance terminal software.

Because these tools are built with modern, memory-efficient languages like Rust and Go, they are incredibly fast and stable. They offer the speed of text with some of the visual benefits of a GUI, making them ideal for managing complex systems over slow connections or handling massive datasets that would cause a graphical app to lag.

A Higher-Resolution Interface for the Mind

Perhaps the most provocative argument Herman makes is that the command line is a "higher-resolution interface for the mind." He explains that using a GUI requires a user to navigate someone else’s mental model of a task. You have to find where the developer hid the "rename" button.

In contrast, the CLI uses language—the most flexible tool humans possess. By typing a command, a user maps their intent directly to an action. This specificity allows for a level of precision that a mouse and cursor simply cannot match. Herman likens it to the difference between pointing at a picture of a sandwich and giving a specific, customized recipe to a chef.

The Future: GPU Acceleration and Collaboration

Finally, the hosts look at the future of the terminal itself. We are no longer limited by the flickering green text of the past. New terminal emulators like Ghostty are using GPU acceleration to render text at 120 frames per second, providing a level of responsiveness that feels like a video game. Meanwhile, tools like Warp are introducing collaborative features, allowing teams to share command histories and use AI search within the terminal.

While there is a natural tension between old-school purists and those embracing these new features, Herman and Corn conclude that both sides are necessary. The old-school tools provide the foundation of stability, while the new tools provide the performance and accessibility needed to keep the terminal relevant for the next sixty years of computing.

Episode #232: The Command Line Resurgence: Why the Terminal is Back

Corn
Hey everyone, and welcome back to My Weird Prompts. I am Corn, and I am sitting here in our house in Jerusalem with my brother.
Herman
Herman Poppleberry, at your service. And we are diving into a topic today that is very near and dear to our housemate Daniel.
Corn
Yeah, Daniel sent us that audio prompt earlier, and you can tell he has been spending a lot of time in the terminal lately. He mentioned being a big fan of something he called Claude Code and this whole idea of a command line resurgence.
Herman
It is a fascinating angle. I think Daniel might be seeing some of the experimental wrappers people are building around these large language models and getting a bit ahead of the official release cycles, but the core of what he is talking about is very real. There is this massive interest right now in how we interact with computers when we strip away the windows, the icons, and the mouse pointers.
Corn
It is funny because to most people, the command line looks like something out of a nineteen eighties movie where a hacker is trying to break into a mainframe. It is just green text on a black background. But Daniel called it Teletext for the modern era.
Herman
I love that analogy. Teletext was so efficient, right? No distractions, just the information you needed. And for those of us who spend our lives in code, the command line interface, or C-L-I, is not just a nostalgic trip. It is a power tool.
Corn
Well, let us start with the history, because Daniel asked how much these predate graphical user interfaces. I mean, obviously they came first, but how far back are we talking?
Herman
We are talking about the very dawn of interactive computing. In the nineteen fifties and early sixties, you did not really have an interface at all. You had punch cards. You would hand a stack of cards to an operator, and they would run them through a room-sized machine.
Corn
Right, so there was no real-time feedback. You just waited for the printout.
Herman
Exactly. The first real step toward what we recognize as a command line came with the development of time-sharing systems in the mid-sixties. Project M-A-C at M-I-T and the development of the Multics operating system were huge. This was when they started using teletype machines, basically electric typewriters that could talk to the computer.
Corn
So instead of cards, you were typing lines of text and getting lines of text back.
Herman
Precisely. And that is where the term T-T-Y comes from, which you still see in Linux today. It stands for Teletypewriter. The shell, which is the program that actually interprets your commands, started to take shape here. Louis Pouzin, a French computer scientist, actually coined the term shell around nineteen sixty-four to describe a program that could call other programs.
Corn
That is such a simple but powerful metaphor. The shell is the outer layer that protects the core of the operating system, the kernel, while letting the user interact with it.
Herman
It is beautiful. And then in the early nineteen seventies, Ken Thompson and Dennis Ritchie at Bell Labs created Unix. This is the big bang moment for the command line. They created the Thompson shell, which was later replaced by the Bourne shell in nineteen seventy-nine. That is the direct ancestor of the Bash shell that most people use today.
Corn
So we are talking about a sixty-year-old lineage. That is incredible longevity for a technology. But Daniel mentioned that as a Linux user, he used to find the syntax frustrating. The minus signs, the parameters, the case sensitivity. Why did we settle on such a difficult way to talk to machines?
Herman
Well, it is only difficult if you think of it as a conversation. If you think of it as a language for composing tools, it is brilliant. There is this concept called the Unix Philosophy. It says that each program should do one thing and do it well. And to make them work together, you use what is called a pipe.
Corn
I remember you explaining pipes to me before. It is that vertical bar character on the keyboard, right?
Herman
Yes. It allows you to take the output of one program and feed it directly as the input to another. So, if I want to find a specific word in a massive file, I do not open a text editor and hit find. I use a tool called cat to read the file, pipe it into a tool called grep to find the word, and maybe pipe that into a tool called sort to organize the results.
Corn
So it is like Lego bricks. You are building a custom solution on the fly.
Herman
Exactly. And that is why developers love it. In a graphical user interface, or G-U-I, you are limited by what the developer put in the menus. If there is no button for what you want to do, you are stuck. In a C-L-I, you are the architect.
Corn
But let us talk about the state of this in twenty twenty-six. Daniel mentioned that even state-of-the-art AI tools are leaning into the terminal. Why is that? If we have these incredibly advanced AI models that can understand natural language, why are we putting them in a text box from nineteen seventy?
Herman
It sounds counterintuitive, but it is about the environment where the work happens. If you are a developer, your terminal is your cockpit. You have your code editor, your version control, and your deployment tools all right there. Switching to a web browser to ask an AI a question is a context switch. It breaks your flow.
Corn
That makes sense. It is about minimizing friction.
Herman
It really is. And there is a second-order effect here. When an AI lives in your terminal, it can see what you are doing. It can see the error message your compiler just spat out. It can see the structure of your file system. It can actually execute commands for you. That is why we are seeing this surge in what people are calling AI agents for the shell.
Corn
You know, I have noticed a lot of people talking about T-U-Is lately as well. Terminal User Interfaces. How do those differ from a standard command line interface?
Herman
That is a great distinction. A C-L-I is strictly line-by-line. You type a command, you get a response. A T-U-I uses the entire terminal window to create a layout. Think of things like htop for monitoring your system or lazygit for managing your code. They use blocks of color and borders made of text characters to create something that looks a bit like a graphical app, but it still runs entirely in text mode.
Corn
Like those old B-B-S systems from the nineties.
Herman
Exactly. And the reason they are making a comeback is because they are incredibly fast. You do not have to wait for a heavy graphical library to load. They are also very stable. If you are logging into a server halfway across the world over a slow connection, a G-U-I might lag or crash. A T-U-I will usually work perfectly.
Corn
Daniel mentioned a tool called Yazi in his notes to us, a file manager written in Rust. I looked it up, and it seems like it is part of this new wave of high-performance terminal tools.
Herman
Yazi is a great example. It is niche, but it is part of a broader trend where developers are using modern languages like Rust or Go to rewrite classic terminal tools. Because these languages are so fast and memory-efficient, they can do things with text that were impossible before. We are seeing terminal file managers that can render image previews and handle thousands of files without breaking a sweat.
Corn
It is interesting that we are using these high-performance languages to build tools for an interface that seems so primitive.
Herman
But is it primitive? That is the question. Think about the resolution of a command. If I want to rename a thousand files in a G-U-I, I have to click a lot, or maybe find a specific batch-rename tool. In a terminal, I can do it with a single line of code using a regular expression. The command line is actually a higher-resolution interface for the mind.
Corn
That is a bold statement, Herman. A higher-resolution interface for the mind? Explain that.
Herman
When you use a G-U-I, you are navigating someone else's mental model of how a task should be done. You are looking for their buttons and their icons. When you use a terminal, you are expressing your intent directly through language. Language is the most flexible and powerful tool humans have ever developed. By using a C-L-I, you are mapping your thoughts directly to actions.
Corn
I see what you mean. It is the difference between pointing at a picture of a sandwich and actually saying, I would like a sourdough bread with extra pickles and no mayo.
Herman
Exactly. The specificity is the superpower.
Corn
So, what about the hardware side of this? Or at least the software that emulates the hardware. We are not using teletypes anymore. We are using terminal emulators. I have heard you talking about things like Warp and Ghostty lately.
Herman
Oh, the world of terminal emulators is exploding right now. For decades, we just used basic terminals like xterm or the default ones that came with our operating systems. But now, we have these modern emulators that are G-P-U accelerated.
Corn
Wait, why do you need a graphics card to render text?
Herman
It sounds ridiculous, right? But modern terminals are doing a lot. They are handling millions of colors, they are rendering complex fonts with ligatures, and they are providing smooth scrolling at one hundred and twenty frames per second. Ghostty, for example, is a project that has been getting a lot of buzz for being incredibly fast and using the G-P-U to make the text feel as responsive as a video game.
Corn
And then there is Warp, which is trying to turn the terminal into a collaborative tool.
Herman
Yeah, Warp is interesting because it treats the terminal more like a modern text editor. It gives you a cursor you can move with a mouse, it has built-in AI search, and you can share your command history with your team. Some purists hate it because it breaks the traditional model, but it is clearly bringing a lot of new people into the command line world.
Corn
It feels like there is a bit of a tension there. Between the old-school philosophy of simple, text-only tools and this new world of G-P-U acceleration and AI integration.
Herman
There is. But I think they are actually feeding each other. The old-school tools give us the foundation of stability and composability. The new tools give us the performance and the ease of use to keep those foundations relevant in twenty twenty-six.
Corn
Let us address one of the things Daniel brought up about CLIs being better for development because they eliminate the complications of a graphical layer. He called it the distraction-free environment. Is that really a significant factor, or is it just a feeling?
Herman
No, it is a very real technical factor. When you build a G-U-I application, a huge percentage of your code is just dedicated to drawing the interface. You have to worry about window scaling, high-D-P-I displays, different operating system themes, and accessibility layers. It is a massive amount of complexity that has nothing to do with the actual logic of your program.
Corn
So by skipping the G-U-I, you are skipping all those potential bugs.
Herman
Exactly. A C-L-I tool is much easier to test and much easier to maintain. It is also much easier to automate. You cannot easily tell a G-U-I app to run itself every night at three in the morning and send you a report. But with a C-L-I, that is just a simple cron job.
Corn
It is about reliability.
Herman
It is. And for the user, that distraction-free element Daniel mentioned is huge. When you are in the terminal, there are no notifications, no pop-ups, no animations. It is just you and the data. It forces a kind of focus that is very hard to find in modern software.
Corn
It is like writing on a typewriter instead of a laptop.
Herman
Very much so. There is a reason why many of the best writers still use very simple text editors or even terminal-based editors like Vim or Neovim. It removes the temptation to fiddle with fonts and margins and lets you focus on the words.
Corn
You mentioned Neovim. We should probably talk about the Language Server Protocol, or L-S-P, because that feels like a major turning point for terminal-based work.
Herman
Oh, absolutely. This is a bit technical, but it is one of the most important developments in the last decade of computing. Historically, if you wanted your text editor to understand a language like Python or Rust, the editor had to have that logic built in. This meant that every editor had to reinvent the wheel for every language.
Corn
That sounds like a lot of wasted effort.
Herman
It was. So Microsoft, of all companies, developed the Language Server Protocol. It basically says, let us separate the editor from the language logic. The language logic lives in a server, and the editor just talks to it over a standard protocol.
Corn
So any editor can talk to any language server?
Herman
Yes. And this was a massive win for the terminal. Suddenly, a simple, lightweight terminal editor like Neovim could have the same powerful features as a massive, heavy I-D-E like Visual Studio. Things like auto-completion, jump-to-definition, and real-time error checking. It leveled the playing field.
Corn
So you get the power of a modern development environment with the speed and focus of a terminal.
Herman
Precisely. It is the best of both worlds.
Corn
Let us move to some practical takeaways for our listeners. If someone is listening to this and they have always been intimidated by that blinking cursor in the black box, where should they start? Is it worth the learning curve in twenty twenty-six?
Herman
I would say it is more worth it now than ever. Not because you have to use it for everything, but because it gives you a deeper understanding of how your computer actually works. My first piece of advice is: do not try to learn it all at once. You do not need to memorize a hundred commands.
Corn
What are the big ones? The essential kit?
Herman
Start with navigation. Learn how to move between folders with c-d, how to list files with l-s, and how to move or copy files with m-v and c-p. Once you can move around comfortably, learn how to use a basic text editor like Nano or Micro.
Corn
Micro is a good recommendation. It feels a lot more like a modern editor with mouse support and familiar keyboard shortcuts.
Herman
It is a great bridge. And then, the real magic happens when you learn about the package manager for your system. Whether it is Homebrew on Mac, or apt on Linux, or Winget on Windows. Being able to install software by just typing a single command is a revelation for most people.
Corn
It definitely beats hunting through websites for download buttons and running installers.
Herman
And if you are feeling adventurous, try a T-U-I. Install something like btop to see your system performance. It is beautiful, it is informative, and it will make you feel like you are actually in control of the machine.
Corn
I think one of the most interesting things Daniel mentioned was the nostalgia. He talked about growing up in the nineties. Do you think our generation has a specific attachment to this aesthetic?
Herman
I think so. We saw the transition. We remember when computers felt a bit more raw and experimental. There is a certain honesty to a terminal. It is not trying to sell you anything. It is not trying to keep you engaged with an algorithm. It is just a tool, waiting for your input.
Corn
There is a beauty in that simplicity.
Herman
There really is. And I think that is why we are seeing this interest from younger developers too. They have grown up in a world of highly polished, very restrictive apps. To them, the terminal feels like a secret world where they can actually see the gears turning. It is empowering.
Corn
You know, it occurs to me that as AI becomes more prevalent, the command line might actually become the primary way we interact with these models. If an AI can understand a complex instruction, it is much easier for it to translate that into a series of terminal commands than to try and navigate a G-U-I.
Herman
That is exactly where we are heading. We are moving toward a world of natural language interfaces that use the command line as their execution layer. You tell the AI what you want, and it writes the shell script to make it happen. The terminal becomes the universal language between humans, AI, and the operating system.
Corn
So in a weird way, the oldest interface is becoming the most future-proof.
Herman
It is the ultimate survivor. It has outlasted floppy disks, C-D-ROMs, and it might even outlast the mouse.
Corn
That is a wild thought. Imagine a world where we go back to just talking to our computers in text, but the computer is finally smart enough to understand us.
Herman
It would be a full-circle moment. From the teletype to the AI agent.
Corn
Well, Herman, this has been a great dive. I think we have covered the history, the philosophy, and the modern state of the CLI. Do you have any final thoughts for Daniel and our listeners?
Herman
Just that the terminal is not a wall; it is a door. It might look intimidating from the outside, but once you step through, you realize you have much more power over your digital life than you ever thought possible. Do not be afraid of the blinking cursor. It is just waiting for you to tell it what to do.
Corn
Well said. And hey, if you are enjoying the show and our deep dives into these weird prompts Daniel sends us, we would really appreciate it if you could leave us a review on your favorite podcast app or on Spotify. It genuinely helps other curious minds find us.
