Name

       condor_preen remove - extraneous files from HTCondor directories

Synopsis

       condor_preen [-mail] [-remove] [-verbose] [-debug]

Description

       condor_preenexamines  the directories belonging to HTCondor, and removes extraneous files and directories
       which may be left over from HTCondor 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  HTCondor  configuration  files.  condor_preenis  intended  to  be  run as user  root or user  condor
       periodically 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 variables  VALID_SPOOL_FILES and  SYSTEM_VALID_SPOOL_FILES , as given by the configuration.
       For  the   LOG  directory,  the  only files removed or reported are those listed within the configuration
       variable  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.

       -debug

          Print extra debugging information as the command executes.

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.
