Question

I would like to use the Ansible lineinfile module (or something similar) to insert a line after every match of a particular regular expression (lineinfile will only insert after the last match).

这似乎非常简单。我先戴谷歌。

这里的解决办法是使用“可使用<代码>replace”模块,采用负头.,以确保一站不住脚。

vars:
  find_this: "Row in the file"
  insert_this: "New line to be inserted"
  filename: "path/to/foo_file.txt"

tasks:
  - name: multiline match and insert
    replace: >
      dest={{ filename }}
      regexp="^({{ find_this }}
)(?!{{ insert_this }})"
      replace="1{{ insert_this }}
"
