module: win_shell
short_description: Execute shell commands on target hosts
version_added: 2.2
description:
     - The C(win_shell) module takes the command name followed by a list of space-delimited arguments.
       It is similar to the M(win_command) module, but runs
       the command via a shell (defaults to PowerShell) on the target host.
     - For non-Windows targets, use the M(shell) module instead.
options:
  free_form:
    description:
      - The C(win_shell) module takes a free form command to run.
      - There is no parameter actually named 'free form'. See the examples!
    type: str
    required: yes
  creates:
    description:
      - A path or path filter pattern; when the referenced path exists on the target host, the task will be skipped.
    type: path
  removes:
    description:
      - A path or path filter pattern; when the referenced path B(does not) exist on the target host, the task will be skipped.
    type: path
  chdir:
    description:
      - Set the specified path as the current working directory before executing a command
    type: path
  executable:
    description:
      - Change the shell used to execute the command (eg, C(cmd)).
      - The target shell must accept a C(/c) parameter followed by the raw command line to be executed.
    type: path
  stdin:
    description:
    - Set the stdin of the command directly to the specified value.
    type: str
    version_added: '2.5'
  no_profile:
    description:
    - Do not load the user profile before running a command. This is only valid
      when using PowerShell as the executable.
    type: bool
    default: no
    version_added: '2.8'
  output_encoding_override:
    description:
    - This option overrides the encoding of stdout/stderr output.
    - You can use this option when you need to run a command which ignore the console's codepage.
    - You should only need to use this option in very rare circumstances.
    - This value can be any valid encoding C(Name) based on the output of C([System.Text.Encoding]::GetEncodings()).
      See U(https://docs.microsoft.com/dotnet/api/system.text.encoding.getencodings).
    type: str
    version_added: '2.10'
notes:
   -  If you want to run an executable securely and predictably, it may be
      better to use the M(win_command) module instead. Best practices when writing
      playbooks will follow the trend of using M(win_command) unless C(win_shell) is
      explicitly required. When running ad-hoc commands, use your best judgement.
   -  WinRM will not return from a command execution until all child processes created have exited.
      Thus, it is not possible to use C(win_shell) to spawn long-running child or background processes.
      Consider creating a Windows service for managing background processes.

# Execute a command in the remote shell; stdout goes to the specified
