Description

dpkg-vendor is a tool to query information about vendors listed in /etc/dpkg/origins.
       /etc/dpkg/origins/default contains information about the current vendor.

       The origin files provide metadata about specific vendors, such as their URL or where to file bug reports,
       and are usually used both to determine the behavior of tools and resulting contents during package builds
       targeting a specific vendor, and to describe the provenance of packages.

       Packages can explicitly declare their vendor by including an Origin field, otherwise the vendor for a
       package without such field is assumed to be the one pointed to by the default origin symbolic link.

       The default symbolic link is also used to denote the origin of the current installation managed by dpkg,
       be that a full distribution or an overlay on top of an existing base system that contains either no
       packaging system or a native one.

       This program was introduced in dpkg 1.15.1.

Environment

DEB_VENDOR
           This  setting defines the current vendor.  If not set, it will discover the current vendor by reading
           /etc/dpkg/origins/default.

       DPKG_COLORS
           Sets the color mode (since dpkg 1.18.5).  The currently accepted values are: auto  (default),  always
           and never.

       DPKG_NLS
           If  set,  it  will  be  used  to  decide  whether  to activate Native Language Support, also known as
           internationalization (or i18n) support (since dpkg  1.19.0).   The  accepted  values  are:  0  and  1
           (default).

Files

Packagingsupport/usr/share/dpkg/vendor.mk
           Makefile snippet that sets the current vendor and its parent into variables, and provides make macros
           to check for derivatives (since dpkg 1.16.1).

Name

           variable or /etc/dpkg/origins/default.
