dpkg-vendor(1)

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 /home/linuxbrew/.linuxbrew/etc/dpkg/origins. /home/linuxbrew/.linuxbrew/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 /home/linuxbrew/.linuxbrew/etc/dpkg/origins/default.

ENVIRONMENT

DEB_VENDOR
    This setting defines the current vendor. If not set, it will discover the current vendor by reading /home/linuxbrew/.linuxbrew/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).
