How do i use regex_findall filter to display partial output of 'sh clock' command?

[Vikram S]

In below output, i want only the 'May 11 2021' to be displayed on screen.

Switch#sh clock

02:42:19.622 Sng Tue May 11 2021

Below is a sample script and used 'regex' filter as an example. How do i modify the script/ incorporate other any other filter such that my above objective is achieved?

- name: GATHER SHOW VERSION

  ios_command: 

    commands: "show clock"

  register: show_clock

- debug: 

    msg: 

    - "{{ show_clock.stdout[0] | regex_findall('.....)"

Thanks,

Vikram

something like   - "{{ show_clock.stdout[0] | regex_findall('[A-Z][a-z]{2}\s[0-9]{2}\s[0-9]{4}')" should work although I am no expert so there may be a better way to do it.   

I found  https://regexone.com/  to be helpful to learn the basics  and https://regex101.com/ for testing.

Hi,

I suspect your script may show ewverything in 'sh clock' output and not the partial output i wanted.  Thanks for the links, will check them.

You expect this based on? First check.

If you must parse dates like that, it requires more data. Is the first
line ('Switch#sh clock') also part of the output? Let's assume so.
And is the month abbreviated or not? From just 'May' we can't tell.
Assuming it is, this works, in this century:

"{{ out | regex_replace(
'(?s).*(Mon|Tue|Wed|Thu|Fri|Sat|Sun)\\s+(Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)\\s+(\\d{1,2})\\s+(20\\d\\d)$',
'\\2 \\3 \\4'
) }}"
