查找将从Windows命令行执行的程序的路径

Finding the path of the program that will execute from the command line in Windows

假设我在系统的c:\abcd\happy\文件夹中安装了一个程序X.EXE。文件夹在系统路径上。现在假设系统上有另一个程序，也称为x.exe，但安装在c:\windows\文件夹中。

是否可以从命令行中迅速发现，如果我输入X.EXE，两个X.EXE中的哪一个将被启动？(但不必在任务管理器中直接搜索或查看流程详细信息)。

也许是某种内置的命令，或者是一些可以做这种事情的程序？：

1	detect_program_path X.EXE

set EXTLIST=%PATHEXT%

if not"%EXTLIST%" =="" goto :extlist_ok
set EXTLIST=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH
:extlist_ok

rem - first look for the file as given (not adding extensions)
for %%i in (%1) do if NOT"%%~$PATHLIST:i"=="" echo %%~$PATHLIST:i

rem - now look for the file adding extensions from the EXTLIST
for %%e in (%EXTLIST%) do @for %%i in (%1%%e) do if NOT"%%~$PATHLIST:i"=="" echo %%~$PATHLIST:i

正如注释中提到的线程，PowerShell中的get-command也可以解决这个问题。例如，您可以键入get-command npm，输出如下：
