       REPORTFILE] [-m ADDRESS] [-k | -n | -N]


       This manual page documents  briefly  the  cruft  command.   Please  see
       /usr/share/doc/cruft/README.gz for more information.

       cruft  is  a  program  that  goes  over  the  Debian packaging system’s
       database, and compares the contents of that with the files actually  on
       your system, and produces a summary of the differences.


       The following options are recognized:

       -h     Show a summary of options and exit.

       -d DRIVES
              Search  only  the  listed  filesystems.   DRIVES  should  be  an
              absolute path, or a quoted,  space-separated  list  of  multiple
              absolute  paths  (eg,  "/  /usr /home"). Multiple -d options are
              allowed as well. If not specified, cruft attempts to  autodetect
              which filesystems to scan.

       --chroots CHROOTS
              Do   not   perform  validity  checks  on  symlinks  under  these
              directories. Useful for whatever  chroots  are  set  up  in  the

       --ignore IGNORES
              Treat  the  directory trees in IGNORES as if they did not exist.
              IGNORES should be an absolute path, or a quoted, space-separated
              list  of  multiple absolute paths. Multiple --ignore options are
              allowed as well.

       -r REPORTFILE
              Output report to REPORTFILE instead of standard output.

       -m ADDRESS
              Mail report to ADDRESS.

       -k     Only cleanup cruft’s spool directory.

       -n     Generate input files  for  reporting,  but  do  not  generate  a

       -N     Only generate a report, based on old input files.

       With  none  of  -k -n or -N cruft performs all the above three actions,
       that is cleans its own spool directory, generates new input  files  and
       produces  a  report.  Please  note  that  cruft never deletes any files
       outside its own spool directory.


       It is possible to get some debugging information from cruft by  setting
       the variable CRUFT_DEBUG to 1. If you need more detailed information on
       what cruft is doing, set it to 2.
