CMD：如何在CMD中转义此powershell命令？

我有以下powershell命令：

(gc c:\foo.xml -Raw) -replace '(?s)(.*)<bar baz="foo" />', '$1LOL' | Out-File c:\foo.xml

但是，powershell命令有太多特殊字符，无论我使用什么转义，都无法正确执行

---

有人能帮我逃过powershell命令，让我把它放在cmd中吗？

我自己找到了答案：

powershell -Command "(gc c:\foo.xml -Raw) -replace '(?s)(.*)<bar baz=\"foo\" />', '$1LOL' | Out-File c:\foo.xml"

powershell-Command”（gcc:\foo.xml-Raw）-替换“（？s）（.*）”，$1LOL“|出文件c:\foo.xml”

诀窍是“用”而不是“用”逃跑

这帮助我找到了答案。

另一种方法是对命令进行Base64编码，并使用

-EncodedCommand

开关：

$CmdLine = @'
(gc c:\foo.xml -Raw) -replace '(?s)(.*)<bar baz="foo" />', '$1LOL' | Out-File c:\foo.xml
'@
$CmdLineBytes = [System.Text.Encoding]::Unicode.GetBytes($CmdLine)
$EncodedCommand = [System.Convert]::ToBase64String($CmdLineBytes)

从

cmd

调用它：

powershell.exe -EncodedCommand KABnAGMAIABjADoAXABmAG8AbwAuAHgAbQBsACAALQBSAGEAdwApACAALQByAGUAcABsAGEAYwBlACAAJwAoAD8AcwApACgALgAqACkAPABiAGEAcgAgAGIAYQB6AD0AIgBmAG8AbwAiACAALwA+ACcALAAgACcAJAAxAEwATwBMACcAIAB8ACAATwB1AHQALQBGAGkAbABlACAAYwA6AFwAZgBvAG8ALgB4AG0AbAA=

这真是太好了！也许您不知道，但不需要从

cmd.exe

运行它。只需使用PowerShell并直接从PowerShell提示符运行PowerShell命令。
