NAME

apt-config - APT Configuration Query program

SYNOPSIS

apt-config [options] [-o config=string] [-c=file] command

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(5) in a manner that is easy to use by scripted applications.

COMMANDS

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

shell

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. .IP 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
