dd-list

DD-LIST(1)						      General Commands Manual							DD-LIST(1)

NAME

       dd-list - nicely list .deb packages and their maintainers

SYNOPSIS

       dd-list [-hiusV] [--help] [--stdin] [--sources Sources_file] [--dctrl] [--version] [--uploaders] [package ...]

DESCRIPTION

       dd-list produces nicely formatted lists of Debian (.deb) packages and their maintainers.

       Input is a list of source or binary package names on the command line (or the standard input if --stdin is given).  Output is a list of the
       following format, where package names are source packages by default:

	      J. Random Developer <jrandom@debian.org>
		     j-random-package
		     j-random-other

	      Diana Hacker <diana@example.org>
		     fun-package
		     more-fun-package

       This is useful when you want, for example, to produce a list of packages that need to attention from their maintainers, e.g., to be rebuilt
       when a library version transition happens.

OPTIONS

       -h, --help
	      Print brief help message.

       -i, --stdin
	      Read package names from the standard input, instead of taking them from the command line. Package names are whitespace delimited.

       -d, --dctrl
	      Read  package  list  from standard input in the format of a Debian package control file. This includes the status file, or output of
	      apt-cache. This is the fastest way to use dd-list, as it uses the maintainer information from the input instead of  looking  up  the
	      maintainer of each listed package.

	      If no Source: line is given, the Package: name is used for output, which might be a binary package name.

       -s, --sources Sources_file
	      Read package information from the specified Sources_files.  This can be given multiple times.

	      If no Sources_files are specified, any files matching /var/lib/apt/lists/*_source_Sources will be used.

       -u, --uploaders
	      Also  list  developers  who  are named as uploaders of packages, not only the maintainers; this is the default behaviour, use --nou-
	      ploaders to prevent it. Uploaders are indicated with "(U)" appended to the package name.

       -nou, --nouploaders
	      Only list package Maintainers, do not list Uploaders.

       -b, --print-binary
	      Use binary package names in the output instead of source package names (has no effect with --dctrl if  the  Package:  line  contains
	      source package names).

       -V, --version
	      Print the version.
