command_module.md

概要

command模块管理带有一系列空格分隔的参数的命令。指定命令在所有选定的节点执行。注意：command模块不通过shell执行，所以环境变量，例如$HOME以及操作符如<，>，|和&不能生效。（如果你需要这些功能，则需要使用shell模块）

案例

# Example from Ansible Playbooks.
- command: /sbin/shutdown -t now

# Run the command if the specified file does not exist.
- command: /usr/bin/make_database.sh arg1 arg2 creates=/path/to/database

# You can also use the 'args' form to provide the options. This command
# will change the working directory to somedir/ and will only run when
# /path/to/database doesn't exist.
- command: /usr/bin/make_database.sh arg1 arg2
  args:
    chdir: somedir/
    creates: /path/to/database
