cruft - Check the filesystem for cruft (missing and unexplained files)


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


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.


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"). Mul‐ tiple -d options are allowed as well. If not specified, cruft attempts to autode‐ tect 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.


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.
