given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for

Do you like files? Do you like magic? If so, this is the module for you! Puppet is a great language but out-of-the-box it expects and demands that you do things The Puppet Way which isn't always possible.

Take for example the following situations:

  • Your maintaining a fleet of brownfield production machines with an unknown state
  • You must follow your installation orders and they say to edit, not replace files
  • Files shared between multiple 'owners' e.g., modules, people, programs, etc
  • You don't want to fully template a file in order to receive upstream fixes
  • You need to do really simple edit(s)!



  • Make a file 'sandwich' (insert data into a point inside the file)
  • Un-make a file 'sandwich'
  • Delete
  • Comment (not *ML)



  • Append data to a file
  • Un-append data to a file
  • Specify match_start - The first line of input to append from, for cases where some data already exists


  • Replace a regular expression
  • Delete a regular expression


  • Prepend data to a file
  • Un-prepend data to a file
  • Specify match_end - The last line of input to prepend to, for cases where some data already exists


  • Find and replace lines of data in a file
  • Un-replace (delete) matching lines
  • Matches all instances of the match regexp and replaces/deletes as requested


  • There is no setup and FileMagic is cross platform! Please create an issue if you find this not to be the case.

  • Not supported by Puppet, Inc.
