为什么$MyInvocation.MyCommand.Name
会在函数中执行时为您提供函数的名称?
根据{{3}},它意味着为您提供脚本文件名。
这是我正在使用的代码:
function startScript
{
$ScriptName = $MyInvocation.MyCommand.Name
$ScriptName
}
$ScriptName = $MyInvocation.MyCommand.Name
$ScriptName
startScript
<#
Output:
testing.ps1
startScript
#>

$MyInvocation
Contains an information about the current command, such as the name,
parameters, parameter values, and information about how the command was
started, called, or "invoked," such as the name of the script that called
the current command.
$MyInvocation is populated only for scripts, function, and script blocks.
You can use the information in the System.Management.Automation.InvocationInfo
object that $MyInvocation returns in the current script, such as the path
and file name of the script ($MyInvocation.MyCommand.Path) or the name of a
function ($MyInvocation.MyCommand.Name) to identify the current command.
This is particularly useful for finding the name of the current script.
如果您对脚本路径感兴趣,请参阅以下段落:
Beginning in Windows PowerShell 3.0, $MyInvocation has the following new
properties.
-- PSScriptRoot: Contains the full path to the script that invoked the
current command. The value of this property is populated only when
the caller is a script.
