       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  con-
       figuration  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.
