# dpkg-vendor

## 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
           **/usr/local/etc/dpkg/origins**.  **/usr/local/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
               **/usr/local/etc/dpkg/origins/default**.
    


## ENVIRONMENT



           **DEB_VENDOR**
               This setting defines the current vendor.  If not set, it will
               discover the current vendor by reading
               **/usr/local/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/local/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).
