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.
