Debian::DpkgLists(3pm)					User Contributed Perl Documentation				    Debian::DpkgLists(3pm)

NAME

       Debian::DpkgLists - scan /var/lib/dpkg/info/*.list for files/patterns

SYNOPSIS

	   my @packages = Debian::DpkgLists->scan_full_path('/full/file/path');
	   my @packages = Debian::DpkgLists->scan_partial_path('file/path');
	   my @packages = Debian::DpkgLists->scan_pattern(qr{freedom$});
	   my @packages = Debian::DpkgLists->scan_perl_mod('Some::Module');

DESCRIPTION

       Debian::DpkgLists is a module for easy searching of dpkg(1)'s package file lists. These are located in /var/lib/dpkg/info/*.list and
       contain a simple list of full file names (including the leading slash).

       There are a couple of different class methods for searching by full or partial path, a regular expression or a Perl module name.

       Note that dpkg's file lists represent only dpkg's idea of what is installed on the system. If you want to also search in packages,
       available from the Debian archive but not installed locally, see Debian::AptContents.

CLASS-METHODS
       scan_full_path ( path )
	   Scans dpkg file lists for files, whose full path is equal to path. Use when you have the full path of the file you want, like
	   "/usr/bin/perl".

	   Returns a (possibly empty) list of packages containing path.

       scan_partial_path ( path )
	   Scans dpkg file lists for files, whose full path ends with path. Use when you only care about the file name or other trailing portion
	   of the full path like "bin/perl" (matches "/usr/bin/perl" and "/sbin/perl").

	   Returns a (possibly empty) list of packages containing files whose full path ends with path.

       scan_pattern ( pattern )
	   Scans dpkg file lists for files, whose full path matched pattern.

	   Returns a (possibly empty) list of packages containing files whose full path matches pattern.

       scan_perl_mod ( Module::Name )
	   Scans dpkg file lists for files, corresponding to given Module::Name. This is a shorthand method for "scan_pattern" with a pattern that
	   matches "/Module/Name.pm$" in all directories in @INC.

	   Returns a (possibly empty) list of packages containing possible Module::Name files.
