how2

how2 is a command‑line utility that lets users ask natural‑language questions about Unix shell tasks and receive concise command suggestions. It operates by invoking either an AI‑driven code‑completion service trained on Bash and PowerShell syntax or, with the ‑s flag, by searching StackOverflow for relevant answers. The tool can be installed via Homebrew, npm, Debian packages, or pre‑built binaries, and it supports proxy configuration through standard environment variables.

The primary audience consists of developers and system administrators who frequently work in terminals and want a faster alternative to opening a browser and manually locating solutions. By typing a query such as “list all files larger than 10 MB,” users receive an immediate command suggestion, and an interactive mode allows them to browse alternative StackOverflow answers and copy the desired snippet.

Distinctive aspects include the dual‑mode operation (AI versus StackOverflow search), the ability to switch to an interactive selection interface with a single key press, and support for multiple platforms and proxy environments, making it a practical addition to everyday shell workflows.
