多线 sed 替换【暂定】

Question

I've been struggling with sed and regexp while dealing with something a little tricky. I want to replace strings in a configuration file, which looks something similar to

configuration {
     key 0   value0
     key 1   value1
     key 2   value2
}

I want to be able to replace the content inside the brackets. There are multiple configuration{} occurrence in the file, however I only ever want to capture the first one. Note that I also know the key names in advance.

I thought of two implementation solution, the first one is the delete everything inside the brackets and to input my data. The second one is to capture each line inside the brackets and replace them with my data.

My main issue is that I'm really struggling with the multi-line. I've tried a lot of things, but nothing close, and couldn't find help I understand online. If someone had a detailed solution, that would be really great.

Also, I'm open to other solutions that would not be sed , as long as they can work on a bash script!

Thanks in advance!

Answer 1

sed cannot capture over newlines, it can only insert them in the new pattern. You need to use awk for this. :)
