How to filter Ansible output from Junos show command(s)

  • 1.  How to filter Ansible output from Junos show command(s)

    Posted 15 days ago
    Hello all...

    I'm new to using ansible in our Juniper environment and have begun chipping away. At this point, I'm just looking to simply filter (cut down) the output returned from a show command.

    For example, I'm using the  junipernetworks.junos.junos_command module to run a 'show version' -  I would like a more concise single line output. Pipes do not work with this module it seems , so (| match "string") is not useful.

    Some older documentation indicated your uptime.stdout_lines can be appended with brackets and a number indicating the line you want to display - ie uptime.stdout_lines[4] - this causes an undefined variable error when running the playbook...and no output is displayed. (see below)

    What is the preferred way to get this done - are there other modules that are more favorable to filtering? Any help and examples are appreciated !  

    My simple playbook is below ,,,, thank you,  Dennis


    TASK [display output] *********************************************************************************************************************************************
    ok: [dining_core] => {
    "uptime.stdout_lines[3]": "VARIABLE IS NOT DEFINED!"
