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.
