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  SPOOLdirectories  as  defined  in   the   HTCondor   configuration   files.
       condor_preenis  intended  to  be  run  as  user rootor user condorperiodically 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 SPOOLdirectory, it always leaves behind the files specified in
       the configuration variables VALID_SPOOL_FILESand SYSTEM_VALID_SPOOL_FILES, as given by the
       configuration. For the LOGdirectory, the only files removed or reported are  those  listed
       within the configuration variable INVALID_LOG_FILESlist. The reason for this difference is
       that, in general, the files  in  the  LOGdirectory  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_ADMINconfiguration 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.
