DESCRIPTION

13       apt-config  is  an internal program used by various portions of the APT
14       suite to provide consistent configurability. It accesses the main  con‐
15       figuration  file  /etc/apt/apt.conf  in a manner that is easy to use by
16       scripted applications.
17
18       Unless the -h, or --help option is given one of the commands below must
19       be present.
20
21       shell  shell  is  used  to  access the configuration information from a
22              shell script. It is given pairs of arguments, the first being  a
23              shell  variable and the second the configuration value to query.
24              As output it lists a series of shell  assignments  commands  for
25              each present value.  In a shell script it should be used like:
26
27
28              OPTS="-f"
29              RES=`apt-config shell OPTS MyApp::Options`
30              eval $RES
31
32              This  will set the shell environment variable $OPTS to the value
33              of MyApp::Options with a default of -f.
34
35              The configuration item  may  be  postfixed  with  a  /[fdbi].  f
36              returns  file  names,  d  returns directories, b returns true or
37              false and i returns an integer. Each of the returns  is  normal‐
38              ized and verified internally.
39
40       dump   Just show the contents of the configuration space.
41

45       options  you  can  override  the  config  file  by using something like
46       -f-,--no-f, -f=no or several other variations.
