NAME
       apt-config - APT Configuration Query program

SYNOPSIS
       apt-config [-hv] [-o=config string] [-c=file] {[shell] | [dump]}

DESCRIPTION
       apt-config is an internal program used by various portions of the APT suite to provide
       consistent configurability. It accesses the main configuration file /etc/apt/apt.conf in a
       manner that is easy to use by scripted applications.

       Unless the -h, or --help option is given one of the commands below must be present.

       shell
	   shell is used to access the configuration information from a shell script. It is given
	   pairs of arguments, the first being a shell variable and the second the configuration
	   value to query. As output it lists a series of shell assignments commands for each
	   present value. In a shell script it should be used like:

	       OPTS="-f"
	       RES=`apt-config shell OPTS MyApp::options`
	       eval $RES
	   This will set the shell environment variable $OPTS to the value of MyApp::options with
	   a default of -f.

	   The configuration item may be postfixed with a /[fdbi]. f returns file names, d
	   returns directories, b returns true or false and i returns an integer. Each of the
	   returns is normalized and verified internally.

       dump
	   Just show the contents of the configuration space.

OPTIONS
       All command line options may be set using the configuration file, the descriptions
       indicate the configuration option to set. For boolean options you can override the config
       file by using something like -f-,--no-f, -f=no or several other variations.

       -h, --help
	   Show a short usage summary.

       -v, --version
	   Show the program version.

       -c, --config-file
	   Configuration File; Specify a configuration file to use. The program will read the
	   default configuration file and then this configuration file. If configuration settings
	   need to be set before the default configuration files are parsed specify a file with
	   the APT_CONFIG environment variable. See apt.conf(5) for syntax information.

       -o, --option
	   Set a Configuration Option; This will set an arbitrary configuration option. The
	   syntax is -o Foo::Bar=bar.  -o and --option can be used multiple times to set
	   different options.

DIAGNOSTICS
       apt-config returns zero on normal operation, decimal 100 on error.
