version_added: "2.4"
author: "Trishna Guha (@trishnag)"
short_description: Run arbitrary commands on a network device
description:
- Sends an arbitrary set of commands to network node and returns the results
read from the device. This module includes an
argument that will cause the module to wait for a specific condition
before returning or timing out if the condition is not met.
options:
commands:
description:
- The commands to send to the remote network device over the
configured provider. The resulting output from the command
is returned. If the I(wait_for) argument is provided, the
module is not returned until the condition is satisfied or
the number of I(retries) has been exceeded.
required: true
wait_for:
description:
- Specifies what to evaluate from the output of the command
and what conditionals to apply. This argument will cause
the task to wait for a particular conditional to be true
before moving forward. If the conditional is not true
by the configured retries, the task fails. See examples.
required: false
default: null
aliases: ['waitfor']
version_added: "2.2"
match:
description:
- The I(match) argument is used in conjunction with the
I(wait_for) argument to specify the match policy. Valid
values are C(all) or C(any). If the value is set to C(all)
then all conditionals in the I(wait_for) must be satisfied. If
the value is set to C(any) then only one of the values must be
satisfied.
required: false
default: all
choices: ['any', 'all']
version_added: "2.2"
retries:
description:
- Specifies the number of retries a command should be tried
before it is considered failed. The command is run on the
target device every retry and evaluated against the I(wait_for)
conditionals.
required: false
default: 10
interval:
description:
- Configures the interval in seconds to wait between retries
of the command. If the command does not pass the specified
conditional, the interval indicates how to long to wait before
trying the command again.
required: false
default: 1
