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

Print on standard output the value of the vendor-specific field for the current vendor.

--help
