([stackoverflow.com](https://stackoverflow.com/questions/304319/is-there-an-equivalent-of-which-on-the-windows-command-line?utm_source=openai))\n\n### Usage Examples\n\n```bat\nwhere cmd.exe\n```\n\n- This will print something like `C:\\Windows\\System32\\cmd.exe` if that's the one that\u2019d run.  \n\n```bat\nwhere python\nwhere notepad.exe\n```\n\n- Finds all matching entries in your directories listed in `%PATH%`.  \n\nIf you want, you can search recursively in a specific path:\n\n```bat\nwhere /r C:\\ someprogram.exe\n```\n\n- This looks through all subdirectories of C:\\ to find a file named `someprogram.exe`. ([superuser.com](https://superuser.com/questions/1523145/how-to-find-out-where-is-a-system-command-in-windows-10?utm_source=openai))\n\n---\n\n## \ud83d\udd27 Fallback for Windows Versions That Don\u2019t Have `where`\n\nIf you're using a version of Windows without `where.exe` (older versions), you can use the `for` command trick to mimic `which`.\n\n```bat\nfor %i in (programName.exe) do @echo %~$PATH:i\n```\n\n- Replace `programName.exe` with whatever you\u2019re searching for (`cmd.exe`, `python`, etc.).  \n- This expands and echoes the actual path if it exists in `%PATH%`. ([stackoverflow.com](https://stackoverflow.com/questions/304319/is-there-an-equivalent-of-which-on-the-windows-command-line?utm_source=openai))\n\n---\n\nIf you had something else in mind by `which.exe` (a different third-party tool, part of a package, etc.), I can pull up info for that too\u2014just let me know!"
