How2 is an AI tool designed specifically for the Unix Command-Line. With its code-completion features, How2 aims to enhance the user experience by proposing relevant shell commands while using the Unix Terminal.

The tool employs multiple artificial intelligence models that are retrained on Bash/Zsh commands to offer its services. The tool is built with emphasis on user safety; it never executes a command on its own but only suggests options to the user, prioritizing the prevention of code injection or misuse.

How2 also allows users to create quick Bash scripts. Furthermore, by simply rewording the prompt, users can optimize usability for specific applications such as 'FOR LOOP', 'BASH SCRIPT', or 'ONE LINER'.

Another unique feature of How2 is the option to pass an '-s' to activate a search on StackOverflow via Google. The tool is also compatible with PowerShell, as it can understand context and align its functions accordingly.

Users can install How2 on MacOSX, UBUNTU / DEBIAN, other Linux versions, and Windows or via NPM package.
