Windows中查找命令的路径 (类似Linux中的which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

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.
