Get indice in file if caracter present

[ryad9...@gmail.com]

Hy all,

I have one file with this content:

1,user1,host1,appli1

2,user2,host2,appli2

My problem is that i want an task who look if {{ ansible_user}},{{inventory_hostname}} == "user1,host1" 

He must return ID of this line "1"

If {{ ansible_user}},{{inventory_hostname}} == "user2,host2"    He must return "2"

How do it please ??

I test command lookup et lineinfile but it's not works :/

Thank you very much !! ;)
