Introduction

Yet another shell (yash) is a command line shell for UNIX-like operating systems. The shell conforms to the POSIX.1-2024 standard (for the most parts), and aims to be more precise than other shells that claim to be POSIX-compliant. Moreover, it has many features that can be used for interactive use, such as command history and command line editing with completion.
