通过命令提示符转义powershell.exe中的引号 [英] Escaping quotes in powershell.exe via command prompt
问题描述
我试图转义引号，但是做一个反斜杠不能转义html引号，像这样： - 注意它是一个正确的双引号不像正常。
I am trying to escape quotes, but doing a backslash does not escape html quotes like this: " <-- notice it's a right double quote unlike the normal ".
例如：
工作正常：
powershell -noexit -command $ str = \hello'123'世界\;写主机$ str
E.g: Works fine: powershell -noexit -command $str = \"hello '123' world\"; write-host $str
无效：
powershell -noexit -command $ str = \ hello'123'world\; write-host $ str
Does not work: powershell -noexit -command $str = \"hello '123'" world\"; write-host $str
如何逃避这个？
推荐答案
使用反引号`来转义特殊的双引号，
Use a backtick ` to escape your special double quote, so this:
powershell -noexit -command $str = \"hello '123'" world\"; write-host $str
变为：
powershell -noexit -command $str = \"hello '123'`" world\"; write-host $str
EDIT：
选项1。如果您更喜欢使用here-strings，可以将以上内容更改为 powershell -file 您的powershell脚本文件。
Option 1. If you prefer using here-strings, you can change the above to powershell -file and run your powershell script file. Use here-strings as much as you want there.
选项2。如果您不想处理您的特殊引号字符，处理应用程序/脚本，您可以切换到使用单引号。在这种情况下，你只需要转义你的单引号，通过加倍它们，像这样：
Option 2. If you prefer not to deal with your special quote character inside calling/processing application/script, you can switch to using single quotes instead. In this case you only need to escape your single quotes, by doubling them, like this:
powershell -noexit -command $str = 'hello ''123''" world'; write-host $str
注意这里我没有对你的双引号字符做任何事，
Notice here I did not do anything to your double quote character, and it works just fine.
所以你的字符串替换代码可能会变得稍微容易阅读和维护，特别是如果编辑器没有正确显示这个字符（像Powershell控制台 - 一个常规的双引号）。
So your string replace code may become slightly easier to read and maintain, especially if the editor does not display this character correctly (like Powershell console does - it shows a regular double quote instead).
