dpkg-divert(1)                 dpkg suite                 dpkg-divert(1)

NAME         top

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

SYNOPSIS         top

       dpkg-divert [option...]  command

DESCRIPTION         top

       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         top

       [--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         top

       --admindir directory
              Set the administrative directory to directory.  Defaults
              to «/usr/local/var/lib/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/usr/local/var/lib/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         top

       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         top

       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         top

       /usr/local/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.

NOTES         top

       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         top

       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
