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 \(lqconffiles\(rq) need to be preserved by \fBdpkg\fP, when installing a newer version of a package which contains those files. .sp .SH COMMANDS .TP .RB [ \-\-add "] \fIfile\fP" Add a diversion for \fIfile\fP. .TP .BI \-\-remove " file" Remove a diversion for \fIfile\fP. .TP .BI \-\-list " glob-pattern" List diversions matching \fIglob-pattern\fP. .TP .BI \-\-listpackage " file" Print the name of the package that diverts \fIfile\fP (since dpkg 1.15.0). Prints LOCAL if \fIfile\fP is locally diverted and nothing if \fIfile\fP is not diverted. .TP .BI \-\-truename " file" Print the real name for a diverted file. . .SH OPTIONS .TP .BI \-\-admindir " directory" Set the \fBdpkg\fP data directory to \fIdirectory\fP (default: \fI/var/lib/dpkg\fP). .TP .BI \-\-divert " divert-to" \fIdivert-to\fP is the location where the versions of \fIfile\fP, as provided by other packages, will be diverted. .TP .B \-\-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. .TP .BI \-\-package " package" \fIpackage\fP is the name of a package whose copy of \fIfile\fP will not be diverted. i.e. \fIfile\fP will be diverted for all packages except \fIpackage\fP. .TP .B \-\-quiet Quiet mode, i.e. no verbose output. .TP .B \-\-rename Actually move the file aside (or back). \fBdpkg\-divert\fP will abort operation in case the destination file already exists. .TP .B \-\-test Test mode, i.e. don't actually perform any changes, just demonstrate. .TP .BR \-? ", " \-\-help Show the usage message and exit. .TP .B \-\-version Show the version and exit. . .SH EXIT STATUS .TP .B 0 The requested action was successfully performed. .TP .B 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. . .SH ENVIRONMENT .TP .B DPKG_ADMINDIR If set and the \fB\-\-admindir\fP option has not been specified, it will be used as the \fBdpkg\fP data directory. .TP .B DPKG_MAINTSCRIPT_PACKAGE If set and the \fB\-\-local\fP and \fB\-\-package\fP options have not been specified, \fBdpkg\-divert\fP will use it as the package name. . .SH FILES .TP .I /var/lib/dpkg/diversions File which contains the current list of diversions of the system. It is located in the \fBdpkg\fP administration directory, along with other files important to \fBdpkg\fP, such as \fIstatus\fP or \fIavailable\fP. .br Note: \fBdpkg\-divert\fP preserves the old copy of this file, with extension \fI\-old\fP, before replacing it with the new one. . .SH NOTES When adding, default is \fB\-\-local\fP and \fB\-\-divert\fP \fIoriginal\fP\fB.distrib\fP. When removing, \fB\-\-package\fP or \fB\-\-local\fP and \fB\-\-divert\fP must match if specified. Directories can't be diverted with \fBdpkg\-divert\fP. Care should be taken when diverting shared libraries, \fBldconfig\fP(8) creates a symbolic link based on the DT_SONAME field embedded in the library. Because \fBldconfig\fP doesn't honour diverts (only \fBdpkg\fP does), the symlink may end up pointing at the diverted library, if a diverted library has the same SONAME as the undiverted one. . .SH EXAMPLES To divert all copies of a \fI/usr/bin/example\fR to \fI/usr/bin/example.foo\fR, i.e. directs all packages providing \fI/usr/bin/example\fR to install it as \fI/usr/bin/example.foo\fR, performing the rename if required: .HP dpkg\-divert \-\-divert /usr/bin/example.foo \-\-rename /usr/bin/example .PP To remove that diversion: .HP dpkg\-divert \-\-rename \-\-remove /usr/bin/example .PP To divert any package trying to install \fI/usr/bin/example\fR to \fI/usr/bin/example.foo\fR, except your own \fIwibble\fR package: .HP dpkg\-divert \-\-package wibble \-\-divert /usr/bin/example.foo \-\-rename /usr/bin/example .PP To remove that diversion: .HP dpkg\-divert \-\-package wibble \-\-rename \-\-remove /usr/bin/example . .SH SEE ALSO .BR dpkg (1).
