我如何问PowerShell的东西在哪里?
例如,"which notepad",它根据当前路径返回notepad.exe运行的目录。

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.

看看这个PowerShell哪个。
这里提供的代码表明:
($Env:Path).Split(";") | Get-ChildItem -filter notepad.exe
如果你有勺子,你可以安装一个直接克隆:
scoop install which
which notepad
我有这个高级功能在我的PowerShell配置文件:
function which {
<#
.SYNOPSIS
Identifies the source of a PowerShell command.
.DESCRIPTION
Identifies the source of a PowerShell command. External commands (Applications) are identified by the path to the executable
(which must be in the system PATH); cmdlets and functions are identified as such and the name of the module they are defined in
provided; aliases are expanded and the source of the alias definition is returned.
.INPUTS
No inputs; you cannot pipe data to this function.
.OUTPUTS
.PARAMETER Name
The name of the command to be identified.
.EXAMPLE
PS C:\Users\Smith\Documents> which Get-Command
Get-Command: Cmdlet in module Microsoft.PowerShell.Core
(Identifies type and source of command)
.EXAMPLE
PS C:\Users\Smith\Documents> which notepad
C:\WINDOWS\SYSTEM32\notepad.exe
(Indicates the full path of the executable)
#>
param(
[String]$name
)
$cmd = Get-Command $name
$redirect = $null
switch ($cmd.CommandType) {
"Alias" { "{0}: Alias for ({1})" -f $cmd.Name, (. { which $cmd.Definition } ) }
"Application" { $cmd.Source }
"Cmdlet" { "{0}: {1} {2}" -f $cmd.Name, $cmd.CommandType, (. { if ($cmd.Source.Length) { "in module {0}" -f $cmd.Source} else { "from unspecified source" } } ) }
"Function" { "{0}: {1} {2}" -f $cmd.Name, $cmd.CommandType, (. { if ($cmd.Source.Length) { "in module {0}" -f $cmd.Source} else { "from unspecified source" } } ) }
"Workflow" { "{0}: {1} {2}" -f $cmd.Name, $cmd.CommandType, (. { if ($cmd.Source.Length) { "in module {0}" -f $cmd.Source} else { "from unspecified source" } } ) }
"ExternalScript" { $cmd.Source }
default { $cmd }
}
}
这似乎是你想要的(我在http://huddledmasses.org/powershell-find-path/):上找到了它
Function Find-Path($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
试试这个例子:
(Get-Command notepad.exe).Path
