apt-config
APT-CONFIG(8) APT 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. 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.
SEE ALSO apt.conf(5)DIAGNOSTICS
apt-config returns zero on normal operation, decimal 100 on error.
