NAME

facterdb - Get a JSON fact set from the facterdb facts database

SYNOPSIS

facterdb <json_filter>

DESCRIPTION

The facterdb tool lets you obtain a JSON-formatted data structure from the facts database that the facterdb library provides. Facts are selected using a filter properly formatted for jgrep.

ENVIRONMENT VARIABLES

FACTERDB_SEARCH_PATHS

List of paths that contain external facts that will complement the
default facterdb database.

When separating paths please use the default path separator character
supported by your OS:

- Unix/Linux/OSX = :
- Windows = ;

Each fact set you create must meet the following requirements:

- A JSON serialized file containing a single Hash of all the facts.
- The facts file must end in .facts
- Must be placed inside some directory. You can organize this directory

however you like.

FACTERDB_SKIP_DEFAULTDB

If this is variable is set (to any value), it will instruct facterdb to
not look at its built-in facts which can be useful should you need to
completely replace which facts are used. You would most likely use this
in combination with the FACTERDB_SEARCH_PATHS environment variable.

FACTERDB_INJECT_SOURCE

If this environment variable is set to any value, the following facts
are injected into all fact sets:

- _facterdb_path: The base name of the file used to load this fact set

e.g. centos-5-i386.facts

- _facterdb_filename : The full path of the file used to load this fact

set e.g. /project/facter-db/centos-5-i386.facts

EXAMPLES

Get facts for facter 2.4 that are either from Debian 7 or RedHat 7:

facterdb 'facterversion=/ˆ2.4\./ and (operatingsystem=Debian and operatingsystemrelease>=7 or operatingsystem=RedHat and operatingsystemrelease=/ˆ7/)'
