NAME
       dpkg-divert - override a	package's version of a file

SYNOPSIS
       dpkg-divert [option...]	command

DESCRIPTION
       dpkg-divert  is	the  utility  used  to	set  up	and update the list of
       diversions.

       File diversions are a way of forcing dpkg(1) not	to install a file into
       its  location,  but  to	a  diverted  location.	Diversions can be used
       through the Debian package scripts to move a file away when it causes a
       conflict.  System  administrators  can  also  use  it  to override some
       package's configuration file, or	 whenever  some	 files	(which	aren't
       marked  as "conffiles") need to be preserved by dpkg, when installing a
       newer version of	a package which	contains those files.

COMMANDS
       [--add] file
	      Add a diversion for file.	 The file is  currently	 not  renamed,
	      see --rename.

       --remove	file
	      Remove a diversion for file.  The	file is	currently not renamed,
	      see --rename.

       --list glob-pattern
	      List diversions matching glob-pattern.

       --listpackage file
	      Print the	name of	the package  that  diverts  file  (since  dpkg
	      1.15.0).	 Prints	 LOCAL if file is locally diverted and nothing
	      if file is not diverted.

       --truename file
	      Print the	real name for a	diverted file.

OPTIONS
       --admindir directory
	      Set the administrative  directory	 to  directory.	  Defaults  to
	      <</var/db/dpkg>>.

       --instdir directory
	      Set  the	installation  directory, which refers to the directory
	      where packages get installed (since dpkg	1.19.2).  Defaults  to
	      <</>>.

       --root directory
	      Set the root directory to	directory, which sets the installation
	      directory	to <<directory>> and the administrative	 directory  to
	      <<directory/var/db/dpkg>>	(since dpkg 1.19.2).

       --divert	divert-to
	      divert-to	 is  the  location  where  the	versions  of  file, as
	      provided by other	packages, will be diverted.

       --local
	      Specifies	that all packages' versions of this file are diverted.
	      This  means,  that there are no exceptions, and whatever package
	      is installed, the	file is	diverted. This can be used by an admin
	      to install a locally modified version.

       --package package
	      package  is the name of a	package	whose copy of file will	not be
	      diverted.	i.e. file will be diverted  for	 all  packages	except
	      package.

       --quiet
	      Quiet mode, i.e. no verbose output.

       --rename
	      Actually	move  the file aside (or back).	dpkg-divert will abort
	      operation	in case	the destination	file already exists.  This  is
	      the  common  behavior used for diversions	of files from the non-
	      Essential	package	set (see --no-rename for more details).

       --no-rename
	      Specifies	that the file should not be renamed  while  adding  or
	      removing	the  diversion	into the database (since dpkg 1.19.1).
	      This is intended for diversions  of  files  from	the  Essential
	      package  set,  where the temporary disappearance of the original
	      file is not  acceptable,	as  it	can  render  the  system  non-
	      functional.   This is the	default	behavior, but that will	change
	      in the dpkg 1.20.x cycle.

       --test Test  mode,  i.e.	 don't	actually  perform  any	changes,  just
	      demonstrate.

       -?, --help
	      Show the usage message and exit.

       --version
	      Show the version and exit.

EXIT STATUS
       0      The requested action was successfully performed.

       2      Fatal  or	unrecoverable error due	to invalid command-line	usage,
	      or interactions  with  the  system,  such	 as  accesses  to  the
	      database,	memory allocations, etc.

ENVIRONMENT
       DPKG_ROOT
	      If  set  and  the	 --instdir  or	--root	options	 have not been
	      specified, it will be used  as  the  filesystem  root  directory
	      (since dpkg 1.19.2).

       DPKG_ADMINDIR
	      If  set  and  the	 --admindir  or	 --root	 options have not been
	      specified, it will be used as the	dpkg data directory.

       DPKG_MAINTSCRIPT_PACKAGE
	      If set and the --local  and  --package  options  have  not  been
	      specified, dpkg-divert will use it as the	package	name.

       DPKG_COLORS
	      Sets the color mode (since dpkg 1.18.5).	The currently accepted
	      values are: auto (default), always and never.

FILES
       /var/db/dpkg/diversions
	      File which contains  the	current	 list  of  diversions  of  the
	      system.  It  is  located	in  the	dpkg administration directory,
	      along with other files important to  dpkg,  such	as  status  or
	      available.
	      Note:  dpkg-divert  preserves  the  old  copy of this file, with
	      extension	-old, before replacing it with the new one.

NOTES
       When adding, default is --local	and  --divert  original.distrib.  When
       removing, --package or --local and --divert must	match if specified.

       Directories can't be diverted with dpkg-divert.

       Care  should  be	 taken	when  diverting	 shared	libraries, ldconfig(8)
       creates a symbolic link based on	the DT_SONAME field  embedded  in  the
       library.	 Because ldconfig doesn't honour diverts (only dpkg does), the
       symlink may end up pointing at the  diverted  library,  if  a  diverted
       library has the same SONAME as the undiverted one.

EXAMPLES
       To  divert  all	copies	of a /usr/bin/example to /usr/bin/example.foo,
       i.e. directs all	packages providing /usr/bin/example to install	it  as
       /usr/bin/example.foo, performing	the rename if required:

       dpkg-divert --divert /usr/bin/example.foo --rename /usr/bin/example

       To remove that diversion:

       dpkg-divert --rename --remove /usr/bin/example

       To   divert   any   package   trying  to	 install  /usr/bin/example  to
       /usr/bin/example.foo, except your own wibble package:

       dpkg-divert --package  wibble  --divert	/usr/bin/example.foo  --rename
	      /usr/bin/example

       To remove that diversion:

       dpkg-divert --package wibble --rename --remove /usr/bin/example
