The Windows Subsystem for Linux (WSL) is a compatibility layer for running Linux binary executables natively on Windows 10 and Windows Server 2019. In simpler terms, it’s a way to run Linux applications and utilities directly on Windows, without needing to boot into a different operating system.
WSL translates Linux system calls to Windows system calls, enabling Linux applications to run on the Windows kernel. It supports both command line and graphical applications and can run a full Linux distribution.
The goal of WSL is to enable developers and system administrators who need to run Linux utilities on Windows machines without having to install a virtual machine or dual-boot setup.
