Hi Racke,
Thanks for the syntax, it is giving an output close to what i want but not
exactly the numbers i want to extract.
*OUTPUT IN DEVICE:*
SWITCH#sh flash: | i bytes
122185728 bytes total (48700416 bytes free)
*MY SCRIPT:*
tasks:
- name: GATHER MASTER FLASH FREE SPACE
ios_command:
commands: "show flash: | i bytes"
register: show_space
- debug:
msg: "{{ show_space | regex_findall('\\d+') | last }}"
*ANSIBLE OUTPUT:*
TASK [debug]
******************************************************************************************************************************************************************************************************
ok: [TEST2960] => {
"msg": "3"
If i give the script without the last keyword, below is output:
- debug:
msg: "{{ show_space | regex_findall('\\d+') }}"
TASK [debug]
******************************************************************************************************************************************************************************************************
ok: [TEST2960] => {
"msg": [
"122185728",
"48700416",
"122185728",
"48700416",
"3"
]
So how can the syntax be modified such that i get only '48700416' in
output? I then plan to 'int' filter to convert it into a integer so that i
can then compare it againt a value.
Thanks,
Vikram
