需要语法与Ansible Shell和命令模块一起使用

Question

The below syntax works fine.

---
- hosts: all

  tasks:
    - name: run this command and ignore the result
      shell: echo "The server is UP since " `uptime`

However when i change shell module to command module I was expecting this to still work.

      command: echo "The server is UP since " `uptime`

But it does not print the uptime value with the command module.

Can I not have the same syntax to work with both the shell as well as the command module ?

Yes, of course, by just manually doing the job that shell: is going to do and wrapping the string in sh -c

- set_fact:
    the_command: sh -c 'echo "The server is UP since `uptime`"'
- command: '{{ the_command }}'
- shell: '{{ the_command }}'
