This file maps each file available in the Debian GNU/Linux system to the package from which it originates. It includes packages from the DIST distribution for the ARCH architecture. You can use this list to determine which package contains a specific file, or whether or not a specific file is available. The list is updated weekly, each architecture on a different day. When a file is contained in more than one package, all packages are listed. When a directory is contained in more than one package, only the first is listed. As all Contents files are shipped compressed, the best way to search quickly for a file is with the Unix `zgrep' utility, as in: `zgrep CONTENTSFILE.gz': $ zgrep -i debian/ Contents-amd64.gz usr/share/IlohaMail/debian/Ilohamail.apache web/ilohamail usr/share/R/debian/r-cran.mk devel/r-base-dev usr/share/apt-listbugs/debian/apt_preferences.rb admin/apt-listbugs usr/share/apt-listbugs/debian/bts.rb admin/apt-listbugs usr/share/apt-listbugs/debian/btssoap.rb admin/apt-listbugs usr/share/apt-listbugs/debian/bug.rb admin/apt-listbugs usr/share/apt-listbugs/debian/mytempfile.rb admin/apt-listbugs This list contains files in all packages, even though not all of the packages are installed on an actual system at once. If you want to find out which packages on an installed Debian system provide a particular file, you can use `dpkg --search ': $ dpkg --search apt-get apt: /usr/bin/apt-get FILE LOCATION
