# There is actually no actual shell module source, when you use 'shell' in ansible,
# it runs the 'command' module with special arguments and it behaves differently.

module: shell
short_description: Execute commands in nodes.
description:
- The M(shell) module takes the command name followed by a list of space-delimited arguments.
It is almost exactly like the M(command) module but runs
the command through a shell (C(/bin/sh)) on the remote node.
version_added: "0.2"
options:
free_form:
description:
- The shell module takes a free form command to run, as a string. There's not an actual
option named "free form". See the examples!
required: true
default: null
creates:
description:
- a filename, when it already exists, this step will B(not) be run.
required: no
default: null
removes:
description:
- a filename, when it does not exist, this step will B(not) be run.
version_added: "0.8"
required: no
default: null
chdir:
description:
- cd into this directory before running the command
required: false
default: null
version_added: "0.6"
executable:
description:
- change the shell used to execute the command. Should be an absolute path to the executable.
required: false
default: null
version_added: "0.9"
notes:
- If you want to execute a command securely and predictably, 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.
