One of the most recommended things is to use "lineinfiles" with some
special attributes for just finding a line in a file.
I have a weird issue with this. If I just lookup one line, like so:
- name: TEST - Check /tmp/out.log
lineinfile:
path: /tmp/out.log
regexp: "^bla"
state: absent
check_mode: yes
changed_when: false
register: checklog
failed_when: not checklog.found
This sequence fails (as expected), because the "bla" line is not in the
file. If I enter a string, which is in the file, it doesn't fail. So far so
good.
Now I wanted to examine several lines, but this never fails. "line1" to
"line4" are in, "bla" not.
But the result is OK...
- name: TEST - Check /tmp/out.log
lineinfile:
path: /tmp/out.log
regexp: "{{ item }}"
state: absent
check_mode: yes
changed_when: false
register: checklog
with_items:
- {item: "^line1"}
- {item: "^line2"}
- {item: "^line3"}
- {item: "^line4"}
- {item: "^bla"}
failed_when: not checklog.found
Does that make sense at all?
