There also always the option of using which. there are actually three ways to access which from Windows powershell, the first (not necessarily the best) wsl -e which command (this requires installation of windows subsystem for Linux and a running distro). B. gnuwin32 which is a port of several gnu binaries in .exe format as standle alone bundled lanunchers option three, install msys2 (cross compiler platform) if you go where it installed in /usr/bin you'll find many many gnu utils that are more up-to-date. most of them work as stand alone exe and can be copied from the bin folder to your home drive somewhere amd added to your PATH.

这似乎是你想要的(我在http://huddledmasses.org/powershell-find-path/):上找到了它

Function Find-Path($Path, [switch]$All = $false, [Microsoft.PowerShell.Commands.TestPathType]$type = "Any")
## You could comment out the function stuff and use it as a script instead, with this line:
#param($Path, [switch]$All = $false, [Microsoft.PowerShell.Commands.TestPathType]$type = "Any")
   if($(Test-Path $Path -Type $type)) {
      return $path
   } else {
      [string[]]$paths = @($pwd);
      $paths += "$pwd;$env:path".split(";")

      $paths = Join-Path $paths $(Split-Path $Path -leaf) | ? { Test-Path $_ -Type $type }
      if($paths.Length -gt 0) {
         if($All) {
            return $paths;
         } else {
            return $paths[0]
         }
      }
   }
   throw "Couldn't find a matching path of type $type"
}
Set-Alias find Find-Path

如果你有勺子，你可以安装一个直接克隆:

scoop install which
which notepad

我喜欢Get-Command |格式列表，或更短，使用别名的两个，只用于powershell.exe:

gcm powershell | fl

你可以找到这样的别名:

alias -definition Format-List

制表符补全使用gcm。

一次列出所有选项:

set-psreadlineoption -editmode emacs

Use:

function Which([string] $cmd) {
  $path = (($Env:Path).Split(";") | Select -uniq | Where { $_.Length } | Where { Test-Path $_ } | Get-ChildItem -filter $cmd).FullName
  if ($path) { $path.ToString() }
}

# Check if Chocolatey is installed
if (Which('cinst.bat')) {
  Write-Host "yes"
} else {
  Write-Host "no"
}

或者这个版本，调用原来的where命令。

这个版本也更好，因为它不局限于bat文件:

function which([string] $cmd) {
  $where = iex $(Join-Path $env:SystemRoot "System32\where.exe $cmd 2>&1")
  $first = $($where -split '[\r\n]')
  if ($first.getType().BaseType.Name -eq 'Array') {
    $first = $first[0]
  }
  if (Test-Path $first) {
    $first
  }
}

# Check if Curl is installed
if (which('curl')) {
  echo 'yes'
} else {
  echo 'no'
}

我通常只输入:

gcm notepad

or

gcm note*

gcm是Get-Command的默认别名。

在我的系统上，gcm note*输出:

[27] » gcm note*
