The **read-cmd-shim** package lets Node.js code determine the target path of a Windows `cmd` shim (the small script created by tools like `npm` to proxy executable commands). It provides both asynchronous (`readCmdShim(path) → Promise`) and synchronous (`readCmdShim.sync(path)`) APIs that behave like `fs.readlink`, supporting both `.cmd`/PowerShell shims and Cygwin‑style shims, and throws a specific `ENOTASHIM` error when the file isn’t a shim. This utility is intended for developers who need to resolve the real executable behind a shim in build scripts, package managers, or other tooling on Windows environments.
