The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.

Dpkg::Compression::Process – run compression/decompression processes DescriptionThis module provides an object oriented interface to run and manage compression/decompression processes. Methodsmy $proc = Dpkg::Compression::Process->new(%opts) Create a new instance of the object. Supported options are “compression” and “compression_level” (see corresponding set_* functions). $proc->set_compression($comp) Select the compression method to use. It errors out if the method is not supported…
Dpkg::Compression::FileHandle – object dealing transparently with file compression Synopsis use Dpkg::Compression::FileHandle; $fh = Dpkg::Compression::FileHandle->new(filename => ‘sample.gz’); print $fh "Something\n"; close $fh; $fh = Dpkg::Compression::FileHandle->new(); open($fh, ‘>’, ‘sample.bz2’); print $fh "Something\n"; close $fh; $fh = Dpkg::Compression::FileHandle->new(); $fh->open(‘sample.xz’, ‘w’); $fh->print("Something\n"); $fh->close(); $fh = Dpkg::Compression::FileHandle->new(filename => ‘sample.gz’); my @lines = <$fh>; close $fh; $fh = Dpkg::Compression::FileHandle->new(); open($fh, ‘<‘,…
Dpkg::Compression – simple database of available compression methods DescriptionThis modules provides a few public funcions and a public regex to interact with the set of supported compression methods. Functionsmy @list = compression_get_list() Returns a list of supported compression methods (sorted alphabetically). compression_is_supported($comp) Returns a boolean indicating whether the give compression method is known and supported….
Dpkg::Checksums – generate and manipulate file checksums DescriptionThis module provides an object that can generate and manipulate various file checksums as well as some methods to query information about supported checksums. Functions@list = checksums_get_list() Returns the list of supported checksums algorithms. $bool = checksums_is_supported($alg) Returns a boolean indicating whether the given checksum algorithm is supported….
Dpkg::Changelog::Parse – generic changelog parser for dpkg-parsechangelog DescriptionThis module provides a single function changelog_parse() which reproduces all the features of dpkg-parsechangelog. FUNCTIONSmy $fields = changelog_parse(%opt) This function will parse a changelog. In list context, it return as many Dpkg::Control object as the parser did output. In scalar context, it will return only the first one….
Dpkg::Changelog::Entry::Debian – represents a Debian changelog entry DescriptionThis object represents a Debian changelog entry. It implements the generic interface Dpkg::Changelog::Entry. Only functions specific to this implementation are described below. Functionsmy @items = $entry->get_change_items() Return a list of change items. Each item contains at least one line. A change line starting with an asterisk denotes the…
Dpkg::Changelog::Entry – represents a changelog entry DescriptionThis object represents a changelog entry. It is composed of a set of lines with specific purpose: an header line, changes lines, a trailer line. Blank lines can be between those kind of lines. Functionsmy $entry = Dpkg::Changelog::Entry->new() Creates a new object. It doesn’t represent a real changelog entry…
Dpkg::Changelog::Debian – parse Debian changelogs DescriptionDpkg::Changelog::Debian parses Debian changelogs as described in the Debian policy (version 3.6.2.1 at the time of this writing). See section “SEE ALSO” for locations where to find this definition. The parser tries to ignore most cruft like # or /* */ style comments, CVS comments, vim variables, emacs local variables…
Dpkg::Changelog – base class to implement a changelog parser DescriptionDpkg::Changelog is a class representing a changelog file as an array of changelog entries (Dpkg::Changelog::Entry). By deriving this object and implementing its parse method, you add the ability to fill this object with changelog entries. FUNCTIONSmy $c = Dpkg::Changelog->new(%options) Creates a new changelog object. $c->load($filename) Parse…
Dpkg::BuildProfiles – handle build profiles DescriptionThe Dpkg::BuildProfiles module provides functions to handle the build profiles. Functionsmy @profiles = get_build_profiles() Get an array with the currently active build profiles, taken from the environment variable DEB_BUILD_PROFILES. set_build_profiles(@profiles) Set @profiles as the current active build profiles, by setting the environment variable DEB_BUILD_PROFILES. my @profiles = parse_build_profiles($string) Parses a…
Dpkg::BuildOptions – parse and update build options DescriptionThe Dpkg::BuildOptions object can be used to manipulate options stored in environment variables like DEB_BUILD_OPTIONS and DEB_BUILD_MAINT_OPTIONS. Functionsmy $bo = Dpkg::BuildOptions->new(%opts) Create a new Dpkg::BuildOptions object. It will be initialized based on the value of the environment variable named $opts{envvar} (or DEB_BUILD_OPTIONS if that option is not set)….
Dpkg::BuildFlags – query build flags DescriptionThe Dpkg::BuildFlags object is used by dpkg-buildflags and can be used to query the same information. Functionsmy $bf = Dpkg::BuildFlags->new() Create a new Dpkg::BuildFlags object. It will be initialized based on the value of several configuration files and environment variables. $bf->load_vendor_defaults() Reset the flags stored to the default set provided…
Dpkg::BuildEnv – track build environment DescriptionThe Dpkg::BuildEnv module is used by dpkg-buildflags to track the build environment variables being used and modified.
