APT-CONFIG(8) APT-CONFIG(8)

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. 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.
