OSINFO-QUERY.C(1)					      Virtualization Support						 OSINFO-QUERY.C(1)

NAME

       osinfo-query - Query information in the database

SYNOPSIS

       osinfo-query [OPTIONS...] TYPE [CONDITION-1 [CONDITION-2 ...]]

DESCRIPTION

       The "osinfo-query" command allows extraction of information from the database. TYPE can be one of "os", "platform", "device", or
       "deployment". With no conditions specified, all entities of the given type will be listed.

	 # List all operating systems
	 $ osinfo-query os
	  Short ID	       | Name	    ...
	 ----------------------+-----------
	  centos-6.0	       | CentOS 6.0 ...
	  centos-6.1	       | CentOS 6.1 ...
	  ...

       Conditions allow filtering based on specific properties of an entity.  For example, to filter only distros from the Fedora Project, use

	 # List all operating systems
	 $ osinfo-query os vendor="Fedora Project"
	  Short ID	       | Name	       ...
	 ----------------------+--------------
	  fedora1	       | Fedora Core 1 ...
	  fedora2	       | Fedora Core 2 ...
	  ...

       The set of fields which are printed can be controlled using the "--fields" command line argument:

	 # List all operating systems
	 $ osinfo-query --fields=short-id,version os vendor="Fedora Project"
	  Short ID	       | Version
	 ----------------------+----------
	  fedora1	       | 1
	  fedora2	       | 2
	  ...
