NAME
dpkg-vendor - queries information about distribution vendors
SYNOPSIS
dpkg-vendor [option...] command
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.
COMMANDS
--is vendor
Exits with 0 if the current vendor is vendor. Otherwise exits with
1.
--derives-from vendor
Exits with 0 if the current vendor distribution is a derivative of
vendor, otherwise exits with 1. It uses the Parent field to browse
all ancestors of the current vendor.
--query field
Print on standard output the value of the vendor-specific field for
the current vendor.
--help
Show the usage message and exit.
--version
Show the version and exit.
OPTIONS
--vendor vendor
Assumes the current vendor is vendor instead of discovering it with
the DEB_VENDOR environment variable or /etc/dpkg/origins/default.
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
Packaging support
/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).
