SYNOPSIS

       cruft [-h] [-d DRIVES] [--chroots CHROOTS] [--ignore IGNORES] [-r REPORTFILE] [-m ADDRESS]
       [-k | -n | -N]

DESCRIPTION

       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.

OPTIONS

       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 system.

       --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 report.

       -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.

ENVIRONMENT VARIABLES

       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.
