This manual page documents briefly the cruft
command. Please see
/usr/share/doc/cruft-common/README.gz for more information.
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:
- 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
- -m ADDRESS
- Mail report to ADDRESS.
- Only cleanup cruft's spool directory.
- Generate input files for reporting, but do not generate a
- Only generate a report, based on old input files.
With none of -k -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
to 1. If you need more detailed information on
what cruft is doing, set it to 2.
