This is the command ucfr that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
ucfr - Update Configuration File Registry: associate packages with configuration files
SYNOPSIS
ucfr [options] <Package> <Path to configuration file>
DESCRIPTION
Where Package is the package associated with the configuration file (and, in some sense,
its owner), and Path to configuration file is the full path to the location (usually under
/etc) where the configuration file lives, and is potentially modified by the end user.
Please note that usually this means that we register actual files, and not symbolic links
to files. ucfr will follow symbolic links and register the real file, and not the
symbolic link.
This script maintains an association between configuration files and packages, and is
meant to help provide facilities that dpkg provides conffiles for configuration files and
not shipped in a Debian package, but handled by the postinst by ucf instead. This script
is idempotent, associating a package to a file multiple times is not an error. It is
normally an error to try to associate a file which is already associated with another
package, but this can be over ridden by using the --force option.
OPTIONS
-h, --help
Print a short usage message
-n, --no-action
Dry run. Print the actions that would be taken if the script is invoked, but take
no action.
-d [n], --debug [n]
Set the debug level to the (optional) level n (n defaults to 1). This turns on
copious debugging information.
-p, --purge
Removes all vestiges of the association between the named package and the
configuration file from the registry. The association must already exist; if the
configuration file is associated with some other package, an error happens, unless
the option --force is also given. In that case, the any associations for the
configuration file are removed from the registry, whether or not the package name
matches. This action is idempotent, asking for an association to be purged multiple
times does not result in an error, since attempting to remove an non-existent
association is silently ignored unless the --verbose option is used (in which case
it just issues a diagnostic).
-v, --verbose
Make the script be very verbose about setting internal variables.
-f, --force
This option forces operations requested even if the configuration file in
consideration is owned by another package. This allows a package to hijack a
configuration file from another package, or to purge the association between the
file and some other package in the registry.
--state-dir /path/to/dir
Set the state directory to /path/to/dir instead of the default /var/lib/ucf. Used
mostly for testing.
USAGE
The most common case usage is pretty simple: a single line invocation in the postinst on
configure, and another single line in the postrm to tell ucfr to forget about the
association with the configuration file on purge (using the --purge option) is all that
is needed (assuming ucfr is still on the system).
