绕过无法识别的转义序列 [英] Bypass Unrecognized Escape Sequence

问题描述

亲爱的，



我正在写一个SSH包装器，看起来很不错。但是，如果我想发送一个复杂的Unix命令，如下所示，我遇到了这样的问题。



cat / proc / cpuinfo | grep^ cpu MHz。*| awk -F：''{print $ 2}''| sed''s @ \。@@ g''| uniq



我可以通过在双引号中添加\来轻松嵌入字符串中的第一个双引号：

Dear all,

I''m writing a SSH wrapper and things are looking pretty good. However, if I want to send a complex Unix command such as below, I''m running into so problems.

cat /proc/cpuinfo | grep "^cpu MHz.*" | awk -F": " ''{print $2}'' | sed ''s@\.@@g'' | uniq

The first double quote i can easily embed in the string by adding \ to the double quote :

string text = "cat /proc/cpuinfo | grep \"^cpu MHz.*\" | awk -F\": \" ''{print $2}'' | sed ''s@\.@@g'' | uniq";

我添加了a \在\^ cpu MHz。* \的双引号之前。这很好，但我想要逃避整个字符串，如

I added a \ right before the double quote at \"^cpu MHz.*\". That works fine, however I''d like to escape an entire string like

''s@\.@@g'' 

有人可以指出我正确的方向。



干杯并再次感谢你。

Can someone please point me in the right direction.

Cheers and thanks one again.

有一篇很好的文章在在C＃中转义：字符，字符串，字符串格式，关键字，标识符 [ ^ ]



基本上，您应该可以使用@符号。



例如：

There''s a good article at Escaping in C#: characters, strings, string formats, keywords, identifiers[^]

Basically, you should be able to use the @ symbol.

For example:

String tempVar = @"cat /proc/cpuinfo | grep "^cpu MHz.*" | awk -F": " '{print
