如何逃避一个bat文件PowerShell的双引号？ [英] How to escape powershell double quotes from a bat file?

问题描述

我想在Windows 7中使用此PowerShell命令运行两个双引号从一个bat文件来替换在一个文件中（temp1.txt）所有双引号：

I'm trying to replace all double quotes in a file (temp1.txt) with two double quotes using this powershell command run from a bat file in Windows 7:

powershell -Command "(gc c:\temp\temp1.txt) -replace '\"', '\"\"' | Out-File -encoding UTF8 c:\temp\temp2.txt"

我不断收到错误：

I keep getting the error:

 'Out-File' is not recognized as an internal or external command.

当我改变命令来替换字母A字母B，它工作正常是这样的：

When I change the command to replace the letter "a" with the letter "b", it works fine like this:

powershell -Command "(gc c:\temp\temp1.txt) -replace 'a', 'b' | Out-File -encoding UTF8 c:\temp\temp2.txt"

我要逃脱双引号，因为整个的powershell -command是一个双引号的字符串内。你如何逃脱双引号？

I need to escape the double quote since the entire powershell -command is within a double quoted string. How do you escape the double quote?

推荐答案

嗯，在这里你需要躲避在命令行中，双引号的字符串内。从我的测试，似乎工作的唯一事情是四双引号引用的参数中：

Hm, here you need to escape the " on the command line, inside a double quoted string. From my testing, the only thing that seems to work is quadruple double quotes """" inside the quoted parameter:

powershell.exe -command "echo '""""X""""'"

于是你的命令行应该是：

So then your command line should be:

powershell -Command "(gc c:\temp\temp1.txt) -replace '""""', '""""""""' | Out-File -encoding UTF8 c:\temp\temp2.txt"

有另一种方式使用PowerShell来处理这个问题，假设你不希望只是把这些命令的文件，并调用它的方法：使用 -En codedCommand 。这可让您采用base64 EN code整个命令或脚本，并把它作为在命令行上一个参数。

There is another way to handle this with powershell, assuming you don't want to just put these commands in a file and call it that way: use -EncodedCommand. This lets you base64 encode your entire command or script and pass it as a single parameter on the command line.

因此​​，这里是你原来的命令：

So here's your original command:

(gc c:\temp\temp1.txt) -replace '"', '""' | Out-File -encoding UTF8 c:\temp\temp2.txt

下面是一个脚本来连接code是：

Here's a script to encode it:

$c = @"
(gc c:\temp\temp1.txt) -replace '"', '""' | Out-File -encoding UTF8 c:\temp\temp2.txt
"@
$b = [System.Text.Encoding]::Unicode.GetBytes($c)
$e = [System.Convert]::ToBase64String($b)

$è现在包含：

所以，你的新的命令行可以是：

So your new command line can be:

没有必要担心什么逃逸
