NAME
cruft - Check the filesystem for cruft (missing and unexplained files)
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-common/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.
