7.4 How can I find out what package produced a particular file?
To identify the package that produced the file named foo execute
either:
-
dpkg --search filename
This searches for filename in installed packages. (This is
(currently) equivalent to searching all of the files having the file extension
of .list in the directory /var/lib/dpkg/info/, and
adjusting the output to print the names of all the packages containing it, and
diversions.)
A faster alternative to this is the dlocate tool.
-
zgrep foo Contents-ARCH.gz
This searches for files which contain the substring foo in their
full path names. The files Contents-ARCH.gz (where ARCH
represents the wanted architecture) reside in the major package directories
(main, non-free, contrib) at a Debian FTP site (i.e. under
/debian/dists/sarge). A Contents file refers only to
the packages in the subdirectory tree where it resides. Therefore, a user
might have to search more than one Contents files to find the
package containing the file foo.
This method has the advantage over dpkg --search in that it will
find files in packages that are not currently installed on your system.
-
apt-file search foo
Similar to the above, it searches files which contain the substring or regular
expression foo in their full path names. The advantage over the
sample above is that there is no need to retrieve the
Contents-ARCH.gz files as it will do this automatically for all
the sources defined in /etc/apt/sources.list when you run (as
root) apt-file update.
