Julia Evans expresses frustration with several common terminal shortcomings. She highlights the difficulty of accurately selecting and copying text, especially across multiple lines or with special characters, often resorting to workarounds like opening the command in a text editor. Additionally, she points out the inconsistency of terminal escape codes leading to unpredictable behavior between different terminals and programs. Finally, she laments the lack of a standardized method to directly interact with and manipulate the output of a previously executed command, requiring awkward copying or screenshotting for further analysis. These limitations, she argues, interrupt her workflow and make the terminal less efficient than it could be.
HN users generally agreed with the author's frustrations regarding terminal emulators. Several commenters pointed to specific pain points like inconsistent copy/paste behavior, difficulties with selecting text, and the lack of proper mouse support across different terminals. Alacritty and Warp were frequently mentioned as modern alternatives attempting to address some of these issues, though some users expressed reservations about Warp's closed-source nature and Electron base. Others discussed the challenges inherent in terminal emulation given its historical baggage and the trade-offs between features, performance, and compatibility. The desire for a truly modern and consistent terminal experience was a recurring theme.
iterm-mcp is a plugin that brings AI-powered control to iTerm2, allowing users to interact with their terminal and REPLs using natural language.

The discussion also touched on the possibility of extending the tool beyond iTerm2 to other terminals. A few users requested a demo video to better understand the functionality. Overall, the reception was positive, with many acknowledging the project's potential while also offering constructive feedback for improvement.
Shunpo is a minimalist Bash tool designed to streamline directory navigation. It learns frequently visited directories and allows users to quickly jump to them using short, custom aliases. By storing these aliases and their corresponding paths in a simple text file, Shunpo avoids complex databases and remains lightweight and portable. It offers basic commands for adding, removing, listing, and navigating to saved locations, simplifying the process of moving between commonly accessed folders within the terminal.
Hacker News users discussed Shunpo's utility and potential drawbacks. Some found its core functionality—quickly jumping to frequently used directories—appealing, especially combined with tools like fzf. Others questioned its value proposition over existing solutions like autojump, z, or fasd, particularly given its reliance on find. Concerns were raised about performance in large directory trees and the security implications of executing arbitrary commands generated from find results. Some suggested improvements, including leveraging shell builtins for better performance and integrating more advanced selection mechanisms. The project's minimalism was both praised and criticized, with some appreciating its simplicity and others desiring more features like directory tracking or the ability to ignore certain paths.
Bunster is a tool that compiles Bash scripts into standalone, statically-linked executables. This allows for easy distribution and execution of Bash scripts without requiring a separate Bash installation on the target system. It achieves this by embedding a minimal Bash interpreter and necessary dependencies within the generated executable. This makes scripts more portable and user-friendly, especially for scenarios where installing dependencies or ensuring a specific Bash version is impractical.
Hacker News users discussed Bunster's novel approach to compiling Bash scripts, expressing interest in its potential while also raising concerns. Several questioned the practical benefits over existing solutions like shc or containers, particularly regarding dependency management and debugging complexity. Some highlighted the inherent limitations of Bash as a scripting language compared to more robust alternatives for complex applications. Others appreciated the project's ingenuity and suggested potential use cases like simplifying distribution of simple scripts or bypassing system-level restrictions on scripting. The discussion also touched upon the performance implications of this compilation method and the challenges of handling Bash's dynamic nature. A few commenters expressed curiosity about the inner workings of the compilation process and its handling of external commands.
/etc/glob was an early Unix mechanism (predating regular expressions) allowing users to create named patterns representing sets of filenames, simplifying command-line operations. These patterns, using globbing characters like * and ?, were stored in /etc/glob and could be referenced by name prefixed with g. While conceptually powerful, /etc/glob suffered from limited wildcard support and was eventually superseded by more powerful and flexible tools like shell globbing and regular expressions. Its existence offers a glimpse into the evolution of filename pattern matching and Unix's pursuit of concise yet powerful user interfaces.
HN commenters discuss the blog post's exploration of /etc/glob in early Unix. Several highlight the post's clarification of the mechanism's purpose, not as filename expansion (handled by the shell), but as a way to store user-specific command aliases predating aliases and shell functions. Some commenters share anecdotes about encountering this archaic feature, while others express fascination with this historical curiosity and the evolution of Unix. The overall sentiment is appreciation for the post's shedding light on a forgotten piece of Unix history and prompting reflection on how modern systems have evolved. Some debate the actual impact and usage prevalence of /etc/glob, with some suggesting it was likely rarely used even in early Unix.
This project demonstrates a surprisingly functional 3D raycaster engine implemented entirely within a Bash script. By cleverly leveraging ASCII characters and terminal output manipulation, it renders a simple maze-like environment in pseudo-3D. The script calculates ray intersections with walls and represents distances with varying shades of characters, creating a surprisingly immersive experience given the limitations of the medium. While performance is understandably limited, it showcases the flexibility and unexpected capabilities of Bash beyond typical scripting tasks.
Hacker News users discuss the ingenuity and limitations of a bash raycaster. Several express admiration for the project's creativity, highlighting the unexpected capability of bash for such a task. Some commenters delve into the technical details, discussing the clever use of shell built-ins and the performance implications of using bash for computationally intensive tasks. Others point out that the "raycasting" is actually a 2.5D projection technique and not true raycasting. The novelty of the project and its demonstration of bash's flexibility are the main takeaways, though its practicality is questioned. Some users also shared links to similar projects in other unexpected languages.
