       apt-config - APT Configuration Query program


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


       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 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:

               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.

           Just show the contents of the configuration space.


       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.




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