如何指导PowerShell导出一个函数名作为cmdlet?

Question

这是

的后续在PowerShell中编写cmdlet

我得到了关于如何将函数声明为cmdlet的链接:

https://learn.microsoft.com/en - us/powershell/scripting/learn/ps101/09 functions?view=powershell - 7.1 #先进功能

使用另一个页面

https://learn.microsoft.com/en us/powershell/module/microsoft.powershell.core/about/about_functions_advanced?view=powershell - 7.1

我试着

function Send-Greeting
{
[CmdletBinding()]
Param(
[Parameter(Mandatory=$true)]
[string] $Name
)
Process
{
Write-Host ("Hello " + $Name + "!")
}
}

我运行了这个脚本，但它没有像预期的那样工作:

PS > .Send-Greeting.ps1
PS > Send-Greeting Joe                                                                                                   Send-Greeting : The term 'Send-Greeting' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was
included, verify that the path is correct and try again.
At line:1 char:1
+ Send-Greeting Joe
+ ~~~~~~~~~~~~~
+ CategoryInfo          : ObjectNotFound: (Send-Greeting:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException

如何将我的新cmd命令导出到PowerShell环境中，以便我可以将其用作内置cmd命令?

Answer 1

三件事:

• 将此代码放入一个模块，即.psm1文件
• 使用export - modulemember cmdlet导出函数
• 使用import - module cmdlet
将该模块导入PowerShell环境

保存为Send-Greeting.psm1:

function Send-Greeting
{
[CmdletBinding()]
Param(
[Parameter(Mandatory=$true)]
[string] $Name
)
Process
{
Write-Host ("Hello " + $Name + "!")
}
}
Export-ModuleMember -Function Send-Greeting

和调用

PS > Import-Module .Send-Greeting.psm1

在那之后，整个事情都工作了:

PS > Send-Greeting -Name Joe 
Hello Joe!
