What How2 is
How2 is a command line AI tool that suggests code and scripts from plain language questions. Instead of leaving your terminal to search for a command, you type what you want to accomplish and How2 returns a matching command or script. It was developed by Claudio Santini and is available for macOS, Ubuntu and Debian, other Linux distributions, and Windows. Installation runs through the official website or through npm, so setup is a short step rather than a project. A free tier covers five queries per day, and a paid subscription is offered for anyone who goes past that limit. The tool is aimed at people who already work in a shell and want faster answers without switching context.
What you can do with it
- Ask for a shell command in everyday words and read the suggestion before running it.
- Draft a Bash script for a repetitive task without writing it line by line.
- Pull StackOverflow results next to the AI answer for background and alternatives.
- Use PowerShell support so Windows sessions get context aware help as well.
Who it is for
- Developers who live in a terminal and want answers without changing windows.
- System administrators who need a command quickly while working through a problem.
- Learners building confidence in Bash or PowerShell who benefit from worked examples.
What to watch out for
How2 only suggests commands. It does not execute anything, which keeps you in control but also means every suggestion still needs a human read before you run it. A wrong flag in a destructive command is still your responsibility, so treat the output as a draft rather than an instruction. The free tier is limited to five queries a day, and the site notes a subscription for anything beyond that, so plan around the cap if you rely on it heavily. Free access rules can change over time, so do not assume the allowance is permanent. There is no graphical interface either, so this is not a fit if you prefer clicking through a visual tool.
