Hi Dick,
I went through example in ansible documentation but was not descriptive
enough and searched extensively on internet but didn't find any examples
for multiline for ansible.
ROUTER#sh run | i boot
boot system flash bootflash:isr4300-universalk9.16.12.04.SPA.bin
boot system flash bootflash:isr4300-universalk9.16.06.04.SPA.bin
Below is a script i wrote using regex_search multiline for checking if
'........9.16.12.04.SPA.bin' is present specifically in 1st line followed
by '.......9.16.06.04.SPA.bin' specifically in 2nd line. But doesn't work.
How should i modify it?
- name: GATHER SHOW VERSION
ios_command:
commands: "sh run | i boot"
register: show_boot
- debug:
msg:
- "{{ show_version.stdout[0] |
regex_search('isr4300-universalk9.16.12.04.SPA.bin ',
'isr4300-universalk9.16.06.04.SPA.bin', multiline=True) }}"
Thanks,
Vikram
