多行的 PowerShell 命令

Question

我有一个看起来像这样的批处理脚本:
测试.bat

@echo off

:: Starts a PowerShell session that starts a PowerShell process with administrator privileges
powershell -noprofile -command "&{$process = start-process powershell -ArgumentList '-noprofile -noexit -file GetTools.ps1' -verb RunAs -PassThru;$process.WaitForExit();}"

我想将“&{ ... }”中的代码分成多行以提高可读性。
This帖子说使用尾随反引号应该可以解决问题，但是当我写:

powershell -noprofile -command "&{`
    $process = start-process powershell -ArgumentList '-noprofile -noexit -file GetTools.ps1' -verb RunAs -PassThru;`
    $process.WaitForExit();`
}"

...也就是说，我用尾随反引号结束每一行，然后我收到以下错误:

Incomplete string token.
At line:1 char:4
+ &{` <<<<
    + CategoryInfo          : ParserError: (`:String) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : IncompleteString

'$process' is not recognized as an internal or external command,
operable program or batch file.
'$process.WaitForExit' is not recognized as an internal or external command,
operable program or batch file.
'}"' is not recognized as an internal or external command,
operable program or batch file.

我究竟做错了什么？
解决方案:

powershell -noprofile -command "&{"^
    "$process = start-process powershell -ArgumentList '-noprofile -noexit -file C:\Dev\Powershell\Sandbox.ps1' -verb RunAs -PassThru;"^
    "$process.WaitForExit();"^
    "}"

Answer 1

你可以试试插入符号 ^表示当前行在下一行继续:

powershell -noprofile -command "&{"^
 "$process = start-process powershell -ArgumentList '-noprofile -noexit -file GetTools.ps1' -verb RunAs -PassThru;"^
 "$process.WaitForExit();"^
 "}"

另请注意前导空间以及关闭和打开 "在每一行上。
