Search upto first occurence of the pattern

[Sivaraman P]

I have the output of command as below

/ps/was-ps/woa/woa_runtime/profiles
/ps/was-ps/woa12/woa_runtime/profiles
/pas/ec1/ukpl/woa_runtime/profiles

From this paths, I need to find the lines upto first occurence of woa or first occuerence of woa*.

Output needed:
/ps/was-ps/woa/
/ps/was-ps/woa12/
/pas/ec1/ukpl/woa_runtime/

Is there anyway to do this in ansible regex_search or anyother filter.

Given the output lines are stored in the list "mylines", try this

- debug:
msg: "{{ mylines|
map('regex_replace', myregex, myreplace)|
list }}"
vars:
myregex: '^(.*?)woa(.*?)/(.*)$'
myreplace: '\g<1>woa\g<2>/'

HTH,

The playbook below works for me

shell> cat playbook.yml
- hosts: localhost
vars:
mylines:
- /ps/was-ps/woa/woa_runtime/profiles
- /ps/was-ps/woa12/woa_runtime/profiles
- /pas/ec1/ukpl/woa_runtime/profiles
tasks:

- debug:
msg: "{{ mylines|map('regex_replace', myregex, myreplace)|list }}"
vars:
myregex: '^(.*?)woa(.*?)/(.*)$'
myreplace: '\g<1>woa\g<2>/'

shell> ansible-playbook playbook.yml
...
TASK [debug] ***
ok: [localhost] => {
"msg": [
"/ps/was-ps/woa/",
"/ps/was-ps/woa12/",
"/pas/ec1/ukpl/woa_runtime/"
]
}
...
