No action is actually taken. -v, --verbose Make the script verbose --three-way Register this file in the cache, and turn on the diff3 option allowing the merging of maintainer changes into a (potentially modified) local configuration file. ) --state-dir bar Set the state directory to bar instead of the default '/var/lib/ucf'. Used mostly for testing. --debconf-ok Indicate that it is ok for ucf to use an already running debconf instance for prompting. --debconf-template bar Specify an alternate, caller-provided debconf template to use for prompting. Usage: $progname -p destination -p, --purge Remove any reference to destination from records By default, the directory the new_file lives in is assumed to be the src-dir, which is where we look for any historical md5sums.
