Documentation

first_found - return first file found from list

Synopsis

  • this lookup checks a list of files and paths and returns the full path to the first combination found.
  • As all lookups, when fed relative paths it will try use the current task’s location first and go up the chain to the containing role/play/include/etc’s location.
  • The list of files has precedence over the paths searched. i.e, A task in a role has a ‘file1’ in the play’s relative path, this will be used, ‘file2’ in role’s relative path will not.

  vars:
    findme:
      - foo
