将类似于正则表达式的符号扩展为多个文字 [英] Expand regex-like notation to multiple literals

问题描述

我有一个带有以下节点的YAML文件:

I've got a YAML file with nodes such as:

group:
  name: test
  permissions:
  - i.can.(create|delete)

我需要用i.can.create和i.can.delete(有很多实例)替换i.can.(create|delete).

I need to replace i.can.(create|delete) with i.can.create and i.can.delete (there are many instances).

我如何轻松地做到这一点?

How can I do this easily?

推荐答案

该想法是用somethinga somethingb等行替换所有something(a|b|c|...).

The idea is to replace all something(a|b|c|...) with lines somethinga somethingb etc.

awk似乎比sed更适合这里:

awk seems to be suited here more than sed:

awk 'BEGIN { FS="[(|)]" ; OFS=""} /\(.*\)/ { for (field=2;field<NF;field++) {print $1,$field ;} ; next ; }1'

这将满足您的要求
