module: shell
short_description: Execute commands in nodes.
description:
     - The shell module takes the command name followed by a list of arguments,
       space delimited. It is almost exactly like the M(command) module but runs
       the command through the user's configured shell on the remote node.
version_added: "0.2"
options:
  (free form):
    description:
      - The command module takes a free form command to run
    required: null
    default: null
  creates:
    description:
      - a filename, when it already exists, this step will NOT be run
    required: false
    default: null
  chdir:
    description:
      - cd into this directory before running the command (0.6 and later)
    required: false
    default: null
examples:
   - code: shell somescript.sh >> somelog.txt
     description: Execute the command in remote shell
notes:
   -  If you want to execute a command securely and predicably, it may be
      better to use the M(command) module instead. Best practices when writing
      playbooks will follow the trend of using M(command) unless M(shell) is
      explicitly required. When running ad-hoc commands, use your best
      judgement.
