----
-module: delegated_serial_command
-short_description: Executes a command on a remote node
-version_added: historical
-description:
- - The M(command) module takes the command name followed by a list
- of space-delimited arguments.
- - The given command will be executed on all selected nodes. It
- will not be processed through the shell, so variables like
- C($HOME) and operations like C("<"), C(">"), C("|"), and C("&")
- will not work (use the M(shell) module if you need these
- features).
- - Creates and maintains a lockfile such that this module will
- wait for other invocations to proceed.
-options:
- command:
- description:
- - the command to run
- required: true
- default: null
- creates:
- description:
- - a filename or (since 2.0) glob pattern, when it already
- exists, this step will B(not) be run.
- required: no
- default: null
- removes:
- description:
- - a filename or (since 2.0) glob pattern, 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
- version_added: "0.6"
- required: false
- default: null
- 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"
- warn:
- version_added: "1.8"
- default: yes
- description:
- - if command warnings are on in ansible.cfg, do not warn about
- this particular line if set to no/false.
- required: false
- lockfile:
- default: yes
- description:
- - the lockfile that will be created
- timeout:
- default: yes
- description:
- - time in milliseconds to wait to obtain the lock
-notes:
- - If you want to run a command through the shell (say you are using C(<),
- C(>), C(|), etc), you actually want the M(shell) module instead. The
- M(command) module is much more secure as it's not affected by the user's
- environment.
- - " C(creates), C(removes), and C(chdir) can be specified after
- the command. For instance, if you only want to run a command if
- a certain file does not exist, use this."
