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.

       --remove	file
	      Remove a diversion for file.

       --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	  dpkg	 data	directory   to	 directory   (default:
	      /var/db/dpkg).

       --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.

       --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_ADMINDIR
	      If set and the --admindir	option has 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.

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
