dpkg-divert(1) dpkg suite dpkg-divert(1)
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/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.
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/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
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
