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.
