sed help:匹配并替换文字"\ n" (不是换行符) [英] sed help: matching and replacing a literal "\n" (not the newline)

问题描述

我有一个文件，其中包含 \ n 的多个实例.

i have a file which contains several instances of \n.

我想用实际的换行符替换它们，但sed无法识别 \ n .

i would like to replace them with actual newlines, but sed doesn't recognize the \n.

我尝试过

sed -r -e 's/\n/\n/'
sed -r -e 's/\\n/\n/'
sed -r -e 's/[\n]/\n/'

以及其他多种转义方法.

and many other ways of escaping it.

sed是否能够识别文字 \ n ?如果可以，怎么办?

is sed able to recognize a literal \n? if so, how?

还有另一个程序可以读取将 \ n 解释为真实换行符的文件吗?

is there another program that can read the file interpreting the \n's as real newlines?

推荐答案

可以请尝试一下

sed -i 's/\\n/\n/g' input_filename
