string, required

Absolute. A missing file is a change in the plan, since an earlier step can create it. Apply fails when it is still missing.

string

Line to keep. It replaces the one line that match finds, or goes at the end of the file.

string, required

Regular expression for the line. More than one matching line fails the check.

string

Check command, as for file. It runs with absent too.

boolean, default false

Remove the matching lines.
