bf_compact — shell script to compact a bogofilter directory
bf_compact bogofilter_directory [wordlist_name...]
bf_compact creates a more compact bogofilter working directory with a dump/load cycle and renames the previous bogofilter_directory to bogofilter_directory.old.
Note: bf_compact cannot be used to process the current working directory, ".", because that cannot be renamed.
If no wordlist_file arguments are given, then bf_compact will use the configured set of wordlists, if the given bogofilter_directory is the same as the configured, or use all *.db files if it is a different directory.
The script exits with status code 0 if everything went well, and nonzero if it encountered trouble.
This script will delete bogofilter_directory.old and all of its contents!
This script expects a SUSv2 compliant shell. Solaris systems should have the SUNWxcu4 package installed (when bogofilter is configured) so that /usr/xpg4/bin/sh can be used.
