NAME

       dpkg-divert - override a package’s version of a file

SYNOPSIS

       dpkg-divert [options] 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.   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/lib/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.

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

FILES

       /var/lib/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.
