module: junos_scp
version_added: "2.5"
author: "Christian Giese (@GIC-de)"
short_description: Transfer files from or to remote devices running Junos
description:
  - This module transfers files via SCP from or to remote devices
    running Junos.
extends_documentation_fragment: junos
options:
  src:
    description:
      - The C(src) argument takes a single path, or a list of paths to be
        transfered. The argument C(recursive) must be C(true) to transfer
        directories.
    required: true
  dest:
    description:
      - The C(dest) argument specifies the path in which to receive the files.
    default: '.'
  recursive:
    description:
      - The C(recursive) argument enables recursive transfer of files and
        directories.
    type: bool
    default: 'no'
  remote_src:
    description:
      - The C(remote_src) argument enables the download of files (I(scp get)) from
        the remote device. The default behavior is to upload files (I(scp put))
        to the remote device.
    type: bool
    default: 'no'
requirements:
  - junos-eznc
  - ncclient (>=v0.5.2)
notes:
  - This module requires the netconf system service be enabled on
    the remote device being managed.
  - Tested against vMX JUNOS version 17.3R1.10.
  - Works with C(local) connections only.
