cruft - Check the filesystem for cruft (missing and unexplained files)
cruft [ FILE ]
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.
If a file is provided, cruft-ng will analyze this single file and
print matching package(s) name(s).
Without any option, cruft-ng will analyze the whole system.
A user can tune execution by providing extra configuration files:
- Do not process paths listed in this file, this can speed-up matching. Example values: /var/schroot/, /var/www/ ... This will override the default /usr/share/cruft/ignore
- Rules (glob-patterns) similar that are similar to those built-in into cruft package. The uppercase files are always processed, the lowercase ones are processed when matching package is installed.
- Shell scripts that will print-out a list of temporary file belonging to a package. The uppercase files are always processed, the lowercase ones are processed when matching package is installed.
It is possible to get some debugging information from cruft by setting the variable DEBUG.
