sed有特殊字符 [英] sed with special characters

问题描述

我有这行要在sed上使用:

I have this line that I want to use sed on:

--> ASD = $start ( *.cpp ) <--

$ start不是变量，我想在上面使用sed并将所有这行替换为:

where $start is not a varaiable, I want to use sed on it and replace all this line with:

ASD = $dsadad ( .cpp ) 

我如何让sed忽略特殊字符，我曾尝试在特殊字符前加反斜杠，但也许我弄错了，有人可以举个例子吗?

How can I make sed ignore special charactars, I tried adding back slash before special characters, but maybe I got it wrong, can some one show me an example?

这就是我想要的:

sed 's/CPPS = \$(shell ls | grep \*\.cpp )/somereplace/' Makefile

推荐答案

sed 's/\$start/\$dsadad/g' your_file
>> ASD = $dsadad ( *.cpp ) 

sed 's/\*//g' your_file
>> ASD = $start ( .cpp ) 

要遵循您的修改:

sed -i 's/ASD = \$start ( \*.cpp )/ASD = \$dsadad ( .cpp )/' somefile
>> ASD = $dsadad ( .cpp )

添加-i(--inplace)以编辑输入文件.

Add the -i (--inplace) to edit the input file.
