我的PowerShell配置文件中有一个名为“which”的函数

function which {
    get-command $args[0]| format-list
}

输出如下：

PS C:\Users\fez> which python

Extension       : .exe

下面是一个我创建的函数，用于查找与Unix命令“WHITE”类似的可执行文件`

app_path_func.cmd：

@ECHO OFF
CLS

FOR /F "skip=2 tokens=1,2* USEBACKQ" %%N IN (`reg query "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\%~1" /t REG_SZ  /v "Path"`) DO (
 IF /I "%%N" == "Path" (
  SET wherepath=%%P%~1
  GoTo Found
 )
)

FOR /F "tokens=* USEBACKQ" %%F IN (`where.exe %~1`) DO (
 SET wherepath=%%F
 GoTo Found
)

FOR /F "tokens=* USEBACKQ" %%F IN (`where.exe /R "%PROGRAMFILES%" %~1`) DO (
 SET wherepath=%%F
 GoTo Found
)

FOR /F "tokens=* USEBACKQ" %%F IN (`where.exe /R "%PROGRAMFILES(x86)%" %~1`) DO (
 SET wherepath=%%F
 GoTo Found
)

FOR /F "tokens=* USEBACKQ" %%F IN (`where.exe /R "%WINDIR%" %~1`) DO (
 SET wherepath=%%F
 GoTo Found
)

:Found
SET %2=%wherepath%
:End

测试：

@ECHO OFF
CLS

CALL "app_path_func.cmd" WINWORD.EXE PROGPATH
ECHO %PROGPATH%

PAUSE

结果：

C:\Program Files (x86)\Microsoft Office\Office15\

Windows没有现货，但它是由Services for Unix提供的，有几个简单的批处理脚本可以完成相同的任务，比如这一个。

只需发布此Windows的单行批处理文件：

C:>type wh.cmd
@for %%f in (%*) do for %%e in (%PATHEXT% .dll .lnk) do for %%b in (%%f%%e) do for %%d in (%PATH%) do if exist %%d\%%b echo %%d\%%b

A测试：

C:>wh ssh
C:\cygwin64\bin\ssh.EXE
C:\Windows\System32\OpenSSH\\ssh.EXE

如果将代码包装在setlocalenableextensions和endlocal中，那就不是一行了。

可以下载为Windows编译的所有UNIX命令，包括从GitHub存储库下载的命令：https://github.com/George-Ogden/UNIX

虽然较新版本的Windows具有where命令，但您也可以使用环境变量修饰符在Windows XP中执行此操作，如下所示：

c:\> for %i in (cmd.exe) do @echo.   %~$PATH:i
   C:\WINDOWS\system32\cmd.exe

c:\> for %i in (python.exe) do @echo.   %~$PATH:i
   C:\Python25\python.exe

您不需要任何额外的工具，也不限于PATH，因为您可以替换任何您希望使用的环境变量（当然是路径格式）。

而且，如果你想要一个能够处理PATHEXT中所有扩展的系统（就像Windows本身一样），这个系统可以做到：

@echo off
setlocal enableextensions enabledelayedexpansion

:: Needs an argument.

if "x%1"=="x" (
    echo Usage: which ^<progName^>
    goto :end
)

:: First try the unadorned filenmame.

set fullspec=
call :find_it %1

:: Then try all adorned filenames in order.

set mypathext=!pathext!
:loop1
    :: Stop if found or out of extensions.

    if "x!mypathext!"=="x" goto :loop1end

    :: Get the next extension and try it.

    for /f "delims=;" %%j in ("!mypathext!") do set myext=%%j
    call :find_it %1!myext!

:: Remove the extension (not overly efficient but it works).

:loop2
    if not "x!myext!"=="x" (
        set myext=!myext:~1!
        set mypathext=!mypathext:~1!
        goto :loop2
    )
    if not "x!mypathext!"=="x" set mypathext=!mypathext:~1!

    goto :loop1
:loop1end

:end
endlocal
goto :eof

:: Function to find and print a file in the path.

:find_it
    for %%i in (%1) do set fullspec=%%~$PATH:i
    if not "x!fullspec!"=="x" @echo.   !fullspec!
    goto :eof

它实际上返回所有可能性，但您可以很容易地针对特定搜索规则进行调整。
