如何用单行创建文件? [英] How to create a file with a single line?

问题描述

文件操作的文档似乎没有提到一个模块将允许我用 one 行创建一个文件.最接近的是 lineinfile 但这个模块也插入标记(所以至少三行).

The documentation for file operations does not seem to mention a module which would allow me to create a file with one line. The closest is lineinfile but this module also inserts markers (so a minimum of three lines).

该行将从变量生成，因此我不想使用传输到目标的本地文件.

The line will be generated from variables so I do not want to use a local file transferred to the target.

有这样的模块吗?或者我应该运行一个 shell 命令，比如

Is there such a module? Or should I run a shell command such as

command: echo {{ myvariable }} > the_file_to_create

生成它?

推荐答案

您可以使用 copy 模块轻松完成，只需使用 force=no 创建一个新的空文件当文件不存在时(如果文件存在，则保留其内容)

You can do it easily with copy module using force=no to create a new empty file only when the file does not yet exist (if the file exists, it's content is preserved)

- name: Copy the content 
  copy:
    content: "{{ myvariable }}"
    dest: /location/of/the/file
    force: no
