PowerShell命令多行

Question

我有一个如下所示的批处理脚本:

TEST.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();}"

为了便于阅读,我想将"&{...}"内的代码拆分为多行.

这篇文章说使用尾随反引用应该可以解决问题,但是当我写下:

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:

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

Answer 1

您可以尝试使用插入符号^来指示当前行继续下一行:

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

请注意领先的空间以及"每条线的关闭和开口.
