SYNOPSIS    [Toc]    [Back]

       apt-config  [  -hv  ]  [ -o=config string ]  [ -c=file ]   [ shell ]  [
       dump ]

DESCRIPTION    [Toc]    [Back]

       apt-config is an internal program used by various portions of  the  APT
       suite  to provide consistent configurability. It accesses the main configuarion
 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    [Toc]    [Back]

       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.
