lineinfile behavior replace line if found, add line if not found?

[Bob Tanner]

Struggling with lineinfile behavior. 

The general question: can lineinfile be used to replace a line in a file if it's found and if it's not found add the line to the file?

I've seen posts saying yes, same saying no, same saying don't use lineinfile, use a template.

Here's the recipe I've been trying:

  lineinfile: >

      dest="/tmp/testfile"

      regexp="(.*){{ item.param }}(.*)?$"

      line='{{ item.param }} {{ item.value }}'

      backrefs="yes"

      state="present"

  with_items:

      - { param: 'testparam', value: 'testvalue' }

The contents of /tmp/testfile

blah blahvalue

foo foovalue

ugh ughvalue

I run the task and "testparam testvalue" does not get added to /tmp/testfile

blah blahvalue

foo foovalue

ugh ughvalue

testvalue wrongvalue

Run the task again and I get what I think is the right output

blah blahvalue

foo foovalue

ugh ughvalue

testvalue testvalue

Hi Bob,

I've used it successfully like this, but I didn't template my regexp.

Cheers,

Using "insertafter=EOF" should do the trick.
