       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  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.

       dump   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. See apt.conf(5) for syntax information.

       -o, --option
              Set  a  Configuration  Option;  This  will   set   an   arbitary
              configuration option. The syntax is -o Foo::Bar=bar.




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