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

       dpkg-divert [option...]  command

       dpkg-divert is the utility used to set up and update the list of diver-

       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 pack-
       age'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.

       [--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.

       --admindir directory
              Set   the   dpkg   data   directory   to   directory   (default:

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

              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

              Quiet mode, i.e. no verbose output.

              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  demon-

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

              Show the version and exit.

              If set and the --admindir option has not been specified, it will
              be used as the dpkg data directory.

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

              File  which  contains the current list of diversions of the sys-
              tem. 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.

       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) cre-
       ates 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.

       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

       To remove that diversion:

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