linux查找文件路徑的命令，Windows中查找命令的路徑 (類似Linux中的which命令)

Linux有個Which命令，用來查找可執行文件的位置。

linux查找文件路徑的命令？例如：which find， 就會從PATH變量的路徑里搜索該命令，返回找到的第一個匹配的結果。

這樣我們就可以知道，我們用的find程序是哪里的。

Windows沒有這樣的指令，我們可以自己寫一個：

@echo off
echo %~dp$PATH:1
@echo on

其它的方法：

apropos命令。
1.where is a direct equivalent:
C:\Users\Joey>where cmd
C:\Windows\System32\cmd.exe

Note that in PowerShell where itself is an alias for Where-Object, thus you need to usewhere.exe in PowerShell.

2.In cmd you can also use for:
C:\Users\Joey>for %x in (powershell.exe) do @echo %~$PATH:x
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe

whereis命令，
3.In PowerShell you have Get-Command and its alias gcm which does the same if you pass an argument (but also works for aliases, cmdlets and functions in PowerShell):
PS C:\Users\Joey> Get-Command where

CommandType???? Name????????? Definition
-----------???? ----????????? ----------
Alias?????????? where???????? Where-Object
Application???? where.exe???? C:\Windows\system32\where.exe

The first returned command is the one that would be executed.
