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  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 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.
