ansible ad-hoc 命令用法

用法：
	ansible  <host-pattern>  [options]
Options:
  -a MODULE_ARGS, --args=MODULE_ARGS
                        module arguments
                        # 模块参数
  --ask-vault-pass      ask for vault password
  						#加密playbook文件时提示输入密码
  -B SECONDS, --background=SECONDS
                        run asynchronously, failing after X seconds(default=N/A)
                        #后台运行任务超时时间,异步运行，X秒之后失败，终止任务
  -C, --check           don't make any changes; instead, try to predict some
                        of the changes that may occur
                        #模拟运行，测试什么内容会改变
  -D, --diff            when changing (small) files and templates, show the
                        differences in those files; works great with --check
                        #当更新的文件数及内容较少时，该选项可显示这些文件不同的地方，该选项结合-C用会有较好的效果
  -e EXTRA_VARS, --extra-vars=EXTRA_VARS
                        set additional variables as key=value or YAML/JSON, if  filename prepend with @
                        # 执行命令时添加额外参数变量
  -f FORKS, --forks=FORKS
                        specify number of parallel processes to use (default=5)
                        #指定并发的任务数，默认为5
  -h, --help            show this help message and exit
  						#显示帮助
  -i INVENTORY, --inventory=INVENTORY, --inventory-file=INVENTORY
                        specify inventory host path or comma separated host list. --inventory-file is deprecated
                        #指定inventory文件或者主机列表(用逗号分隔)
  -l SUBSET, --limit=SUBSET
                        further limit selected hosts to an additional pattern
                        #指定运行的主机
  --list-hosts          outputs a list of matching hosts; does not execute anything else
  						#列出匹配的主机，不执行任何操作
  -m MODULE_NAME, --module-name=MODULE_NAME
                        module name to execute (default=command)
                        #指定模块，默认为command
  -M MODULE_PATH, --module-path=MODULE_PATH
                        prepend colon-separated path(s) to module library (default=~/.ansible/plugins/modules:/usr/share/ansible/plugins/modules)
                        #指定模块路径
  -o, --one-line        condense output
  						#压缩输出，标准输出至一行
  --playbook-dir=BASEDIR
                        Since this tool does not use playbooks, use this as a substitute playbook directory.This sets the relative path for many features including roles/ group_vars/ etc.
                        #指定playbook目录路径
  -P POLL_INTERVAL, --poll=POLL_INTERVAL
                        set the poll interval if using -B (default=15)
                        #定期返回后台任务进度
  --syntax-check        perform a syntax check on the playbook, but do not execute it
  						#对playbook进行语法检查，不执行
  -t TREE, --tree=TREE  log output to this directory
  						#输出信息至TREE目录下，结果文件以远程主机命名
  --vault-id=VAULT_IDS  the vault identity to use
  --vault-password-file=VAULT_PASSWORD_FILES
                        vault password file
                        #
  -v, --verbose         verbose mode (-vvv for more, -vvvv to enable connection debugging)
  						#显示详情
  --version             show program's version number, config file location, configured module search path, module location,executable location and exit
  						#显示版本信息

                        override the connection timeout in seconds(default=10)
                        #指定连接超时时间
