npiperelay is a free utility designed for Windows that facilitates interaction with named pipes from the Windows Subsystem for Linux (WSL). This tool enhances compatibility between command-line tools and Windows named pipes, enabling users to relay information seamlessly. By connecting stdin and stdout to processes in WSL, npiperelay streamlines the workflow for developers and system administrators who rely on both Windows and Linux environments.

The program leverages socat within the WSL distro to effectively communicate with named pipes used by Windows processes. This functionality is particularly useful for those who need to integrate applications across different systems, making npiperelay a valuable addition to the toolkit of any user working in a mixed operating system environment.
