Name
       condor_preen remove - extraneous files from Condor directories

Synopsis
       condor_preen [-mail] [-remove] [-verbose]

Description
       condor_preenexamines  the  directories belonging to Condor, and removes extraneous files and directories which may be left over from Condor
       processes which terminated abnormally either due to internal errors or a system crash. The directories checked are the  LOG  ,	EXECUTE  ,
       and   SPOOL directories as defined in the Condor configuration files. condor_preenis intended to be run as user	root or user  condor peri-
       odically as a backup method to ensure reasonable file system cleanliness in the face of errors. This is done automatically  by  default	by
       the condor_masterdaemon. It may also be explicitly invoked on an as needed basis.

       When  condor_preencleans the  SPOOL directory, it always leaves behind the files specified in the configuration variable  VALID_SPOOL_FILES
       as given by the configuration. For the  LOG directory, the only files removed or reported are those listed within the  configuration  vari-
       able   INVALID_LOG_FILES  list. The reason for this difference is that, in general, the files in the  LOG directory ought to be left alone,
       with few exceptions. An example of exceptions are core files. As there are new log files introduced regularly, it is less effort to specify
       those that ought to be removed than those that are not to be removed.

Options
       -mail

	  Send mail to the user defined in the	PREEN_ADMIN configuration variable, instead of writing to the standard output.

       -remove

	  Remove the offending files and directories rather than reporting on them.

       -verbose

	  List all files found in the Condor directories, even those which are not considered extraneous.

Exit Status
       condor_preenwill exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
