Ruby字符串转义字符 [英] Ruby string escape characters

问题描述

我想将下面的引用字符串完全按照原样获取到字符串中，但是我正在跳过Ruby所需的转义序列。 mycommand.cmd 真的是powershell.exe的包装器，所以我想保留引号之间的所有内容，并且保持已经存在的转义字符。

I want to get the quoted string in the line below into a string exactly as-is, but I am tripping on the necessary escape sequences for Ruby. mycommand.cmd is really a wrapper for powershell.exe so I want to preserve everything between the quotes, and hold onto the escape characters that are already there.

mycommand.cmd "^|foreach-object { \"{0}=={1}\" -f $_.Name, $_.Found }"

推荐答案

使用单引号： / p>

Use single quotes :

ruby-1.9.3-p0 :001 > '^|foreach-object { \"{0}=={1}\" -f $.Name, $.Found }'
 => "^|foreach-object { \\\"{0}=={1}\\\" -f $.Name, $.Found }" 

单引号中唯一的转义字符是： \'和 \\

The only escape characters in single quotes are : \' and \\
