command => ''<your command>'',
onlyif => ''/usr/bin/test -f

Run command unless file exists
exec {
command => ''<your command>'',
creates => ''/path/to/file'',

You might want to rephrase your question, as it is not obvious, at least not to me. Mohamed.

The ''creates'' attribute looks for something to exist at the specified path. A symlink, even if broken, is still a file. These hypotheticals are simple to test out on your own. To test this case on any puppet client, first create a class: #test.pp: class test { exec { ''touch /opt/test.did.run'': creates => ''/opt/test.link'' } } Then create a symlink to a non-existent file: ln -s /opt/nada /opt/test.link Finally: puppet apply test.pp /opt/test.did.run won''t be created. -- Peter M.

Must be something amiss with the above manifest. Even when the target is missing it wasn''t running the exec. The following code will run the exec if the target is a broken symlink but will not run it if the target it a valid symlink: puppet apply -e ''exec { "/bin/touch /opt/exec.did.run": creates => "/opt/test.link" }'' So, again, my former conclusion was incorrect. ''creates'' appears to be smart enough to recognize a broken symlink as a missing file. -- Peter M.

''creates'' appears to be smart enough to recognize a broken symlink as a missing file.I don''t call that "smart", I call it "buggy". The target of a symlink is not the symlink itself. Even a broken symlink named in an Exec''s ''creates'' should be sufficient to prevent that Exec from running. At best, the documentation is inadequate. I encourage you to file an issue report.
