command-instead-of-shell¶
This rule identifies uses of shell
modules instead of a command
one when
this is not really needed. Shell is considerably slower than command and should
be avoided unless there is a special need for using shell features, like
environment variable expansion or chaining multiple commands using pipes.
Problematic Code¶
---
- name: Problematic example
hosts: localhost
tasks:
- name: Echo a message
ansible.builtin.shell: echo hello # <-- command is better in this case
changed_when: false
Correct Code¶
---
- name: Correct example
hosts: localhost
tasks:
- name: Echo a message
ansible.builtin.command: echo hello
changed_when: false
Note
This rule can be automatically fixed using --fix
option.
