DESCRIPTION

14       apt-config  is  an internal program used by various portions of the APT
15       suite to provide consistent configurability.  It accesses the main con‐
16       figuration file /etc/apt/apt.conf(5) in a manner that is easy to use by
17       scripted applications.

COMMANDS

21       Unless the -h, or --help option is given, one  of  the  commands  below
22       must be present.
23
24       shell  Used  to  access  the  configuration  information  from  a shell
25              script.  It is given pairs of arguments, the first being a shell
26              variable  and  the  second the configuration value to query.  As
27              output it lists a series of shell assignments commands for  each
28              present value. In a shell script it should be used like:
29
30              OPTS="-f"
31              RES=`apt-config shell OPTS MyApp::Options`
32              eval $RES
33
34              This  will set the shell environment variable $OPTS to the value
35              of MyApp::Options with a default of -f.  .IP  The  configuration
36              item  may  be postfixed with a /[fdbi].  f returns file names, d
37              returns directories, b returns true or false and  i  returns  an
38              integer.   Each of the returns is normalized and verified inter‐
39              nally.
