How2 for Web

Overview of the tool

How2 is a subscription web app that helps Unix command-line users by offering context-aware shell suggestions. It provides relevant command examples and templates while you work in a terminal environment, speeding common tasks without taking control of your system.

Main capabilities

• Suggests relevant shell commands in real time tailored to your Bash or Zsh workflow
• Generates quick Bash script scaffolding to jumpstart automation tasks
• Lets you refine results simply by rephrasing your query to get more precise suggestions
• Includes an optional Stack Overflow–based lookup that you can enable with a simple flag
• Never runs commands automatically, reducing the risk of harmful or unexpected actions

Security and behavior

The application is deliberately read-only with respect to executing tasks: it provides commands and examples but will not execute them on your behalf. This design reduces exposure to command injection and accidental destructive operations. Users always retain final control over what gets run in their environment.

Workflow and productivity improvements

• Provides instant command recommendations while you’re composing or debugging in a shell
• Offers quick ways to iterate on search prompts for better, narrower results
• Supports rapid assembly of scripts so repetitive tasks can be automated faster
• Augments local troubleshooting with optional community-sourced examples via the Stack Overflow flag

Platform support and access

How2 works across major desktop platforms, including macOS, Ubuntu (and other Linux distributions), and Windows, giving developers a consistent assistant regardless of their setup. Access requires a subscription to the web service, which hosts the AI-backed suggestion engine and delivers updates centrally.
