NAME

   dget -- Download Debian source and binary packages

SYNOPSIS

   dget [options] URL ...
   dget [options] [--all] package[=version] ...

DESCRIPTION

   dget downloads Debian packages.  In the first form, dget fetches the
   requested URLs.  If this is a .dsc or .changes file, then dget acts as
   a source-package aware form of wget: it also fetches any files
   referenced in the .dsc/.changes file.  The downloaded source is then
   checked with dscverify and, if successful, unpacked by dpkg-source.

   In the second form, dget downloads a binary package (i.e., a .deb file)
   from the Debian mirror configured in /etc/apt/sources.list(.d).  Unlike
   apt-get install -d, it does not require root privileges, writes to the
   current directory, and does not download dependencies.  If a version
   number is specified, this version of the package is requested.  With
   --all, the list of all binaries for the source package package is
   extracted from the output of "apt-cache showsrc package".

   In both cases dget is capable of getting several packages and/or URLs
   at once.

   (Note that .udeb packages used by debian-installer are located in
   separate packages files from .deb packages. In order to use .udebs with
   dget, you will need to have configured apt to use a packages file for
   component/debian-installer).

   Before downloading files listed in .dsc and .changes files, and before
   downloading binary packages, dget checks to see whether any of these
   files already exist.  If they do, then their md5sums are compared to
   avoid downloading them again unnecessarily.  dget also looks for
   matching files in /var/cache/apt/archives and directories given by the
   --path option or specified in the configuration files (see below).
   Finally, if downloading (.orig).tar.gz or .diff.gz files fails, dget
   consults apt-get source --print-uris.  Download backends used are curl
   and wget, looked for in that order.

   dget was written to make it easier to retrieve source packages from the
   web for sponsor uploads.  For checking the package with debdiff, the
   last binary version is available via dget package, the last source
   version via apt-get source package.

OPTIONS

   -a, --all
       Interpret package as a source package name, and download all
       binaries as found in the output of "apt-cache showsrc package".  If
       package is arch-qualified, then only binary packages which are
       "Arch: all", "Arch: any", or "Arch: $arch" will be downloaded.

   -b, --backup
       Move files that would be overwritten to ./backup.

   -q, --quiet
       Suppress wget/curl non-error output.

   -d, --download-only
       Do not run dpkg-source -x on the downloaded source package.  This
       can only be used with the first method of calling dget.

   -x, --extract
       Run dpkg-source -x on the downloaded source package to unpack it.
       This option is the default and can only be used with the first
       method of calling dget.

   -u, --allow-unauthenticated
       Do not attempt to verify the integrity of downloaded source
       packages using dscverify.

   --build
       Run dpkg-buildpackage -b -uc on the downloaded source package.

   --path DIR[:DIR ...]
       In addition to /var/cache/apt/archives, dget uses the colon-
       separated list given as argument to --path to find files with a
       matching md5sum.  For example: "--path
       /srv/pbuilder/result:/home/cb/UploadQueue".  If DIR is empty (i.e.,
       "--path ''" is specified), then any previously listed directories
       or directories specified in the configuration files will be
       ignored.  This option may be specified multiple times, and all of
       the directories listed will be searched; hence, the above example
       could have been written as: "--path /srv/pbuilder/result --path
       /home/cb/UploadQueue".

   --insecure
       Allow SSL connections to untrusted hosts.

   --no-cache
       Bypass server-side HTTP caches by sending a Pragma: no-cache
       header.

   -h, --help
       Show a help message.

   -V, --version
       Show version information.

CONFIGURATION VARIABLES

   The two configuration files /etc/devscripts.conf and ~/.devscripts are
   sourced by a shell in that order to set configuration variables.
   Command line options can be used to override configuration file
   settings.  Environment variable settings are ignored for this purpose.
   The currently recognised variable is:

   DGET_PATH
       This can be set to a colon-separated list of directories in which
       to search for files in addition to the default
       /var/cache/apt/archives.  It has the same effect as the --path
       command line option.  It is not set by default.

   DGET_UNPACK
       Set to 'no' to disable extracting downloaded source packages.
       Default is 'yes'.

   DGET_VERIFY
       Set to 'no' to disable checking signatures of downloaded source
       packages.  Default is 'yes'.

EXAMPLES

   Download all .deb files for the previous version of a package and run
   debdiff on them:

     dget --all mypackage=1.2-1
     debdiff --from *_1.2-1_*.deb --to *_1.2-2_*.deb

BUGS AND COMPATIBILITY

   dget package should be implemented in apt-get install -d.

   Before devscripts version 2.10.17, the default was not to extract the
   downloaded source. Set DGET_UNPACK=no to revert to the old behaviour.
