如何用BASH中的递增数字替换所有匹配项? [英] How to replace all matches with an incrementing number in BASH?

问题描述

我有一个像这样的文本文件:

I have a text file like this:

AAAAAA this is some content.
This is AAAAAA some more content AAAAAA. AAAAAA
This is yet AAAAAA some more [AAAAAA] content.

我需要用递增的数字替换所有出现的AAAAAA，例如，输出看起来像这样:

I need to replace all occurrence of AAAAAA with an incremented number, e.g., the output would look like this:

1 this is some content.
This is 2 some more content 3. 4
This is yet 5 some more [6] content.

如何用一个递增的数字替换所有匹配项?

推荐答案

这是一种实现方法:

$ awk '{for(x=1;x<=NF;x++)if($x~/AAAAAA/){sub(/AAAAAA/,++i)}}1' file
1 this is some content.
This is 2 some more content 3. 4
This is yet 5 some more [6] content.
