The output is similar to <application>bogofilter -vv</application>. Finally, hapaxes (tokens which were only seen once) and pure tokens (tokens which were encountered only in ham or only in spam) are counted. </para> <para> The <option>-l <replaceable>file</replaceable></option> option tells <application>bogoutil</application> to load the data from <option>stdin</option> into the database file. If the database file exists, <option>stdin</option> data is merged into the database file, with counts added up. </para> <para>The <option>-m</option> option tells <application>bogoutil</application> to perform maintenance functions on the specified database, i.e. discard tokens that are older than desired, have counts that are too small, or sizes (lengths) that are too long or too short. </para> <para> The <option>-w <replaceable>file</replaceable></option> option tells <application>bogoutil</application> to display token information from the database file. The option takes an argument, which is either the name of the wordlist (usually wordlist.db) or the name of the directory containing it. Tokens can be listed on the command line or piped to <application>bogoutil</application>. When there are extra arguments on the command line, <application>bogoutil</application> will use them as the tokens to lookup. If there are no extra arguments, <application>bogoutil</application> will read tokens from <option>stdin</option>. </para> <para> The <option>-p <replaceable>file</replaceable></option> option tells <application>bogoutil</application> to display the database information for one or more tokens. The display includes a probability column with the token's spam score (computed using <application>bogofilter</application>'s default values). Option <option>-p</option> takes the same arguments as option <option>-w</option> . </para> <para>The <option>-r <replaceable>file</replaceable></option> option tells <application>bogoutil</application> to recalculate the ROBX value and print it as a six-digit fraction. </para> <para>The <option>-R <replaceable>file</replaceable></option> option does the same as <option>-r</option>, but prints more information and saves the result in the training database. </para> <para>The <option>-I <replaceable>file</replaceable></option> option tells <application>bogoutil</application> to read its input from <replaceable>file</replaceable> rather than stdin. </para> <para>The <option>-O <replaceable>file</replaceable></option> option tells <application>bogoutil</application> to write its output to <replaceable>file</replaceable> rather than stdout. </para> <para> The <option>-v</option> option produces verbose output on <option>stderr</option>. This option is primarily useful for debugging. </para> <para>The <option>-C</option> inhibits reading configuration files and lets <application>bogoutil</application> go with the defaults.</para> <para>The <option>--config-file <replaceable>file</replaceable></option> option tells <application>bogoutil</application> to read <replaceable>file</replaceable> instead of the standard configuration file.</para> <para>The <option>-D</option> redirects debug output to stdout (it usually goes to stderr).</para> <para>The <option>-x <replaceable>flags</replaceable></option> option sets debugging flags.</para> <para> Option <option>-n</option> stands for "replace non-ascii characters". It will replace characters with the high bit (0x80) by question marks. This can be useful if a word list has lots of unreadable tokens, for example from Asian spam. The "bad" characters will be converted to question marks and matching tokens will be combined when used with <option>-m</option> or <option>-l</option>, but not with <option>-d</option>. </para> <para> Option <option>-a age</option> indicates an acceptable token age, with older ones being discarded. The age can be a date (in form YYYYMMMDD) or a day count, i.e. discard tokens older than <option>age</option> days. </para> <para> Option <option>-c value</option> indicates that tokens with counts less than or equal to <option>value</option> are to be discarded. </para> <para> Option <option>-s min,max</option> is used to discard tokens based on their size, i.e. length. All tokens shorter than <option>min</option> or longer than <option>max</option> will be discarded. </para> <para> Option <option>-y date</option> is specifies the date to give to tokens that don't have dates. The format is YYYYMMDD. </para> <para>The <option>-h</option> option prints the help message and exits.</para> <para>The <option>-V</option> option prints the version number and exits.</para> </refsect1> <refsect1 id="environment_maintenance"> <title>ENVIRONMENT MAINTENANCE</title> <para>The <option>--db-checkpoint <replaceable>dir</replaceable></option> option causes <application>bogoutil</application> to flush the buffer caches and checkpoint the database environment.</para> <para>The <option>--db-list-logfiles <replaceable>dir</replaceable></option> option causes <application>bogoutil</application> to list the log files in the environment. Zero or more keywords can be added or combined (separated by whitespace) to modify the behavior of this mode. The default behavior is to list only inactive log files with relative paths. You can add <option>all</option> to list all log files (inactive and active). You can add <option>absolute</option> to switch the listing to absolute paths. </para> <para>The <option>--db-prune <replaceable>dir</replaceable></option> option causes <application>bogoutil</application> to checkpoint the database environment and remove inactive log files.</para> <para>The <option>--db-recover <replaceable>dir</replaceable></option> option runs a regular database recovery in the specified database directory. If that fails, it will retry with a (usually slower) catastrophic database recovery. If that fails, too, your database cannot be repaired and must be rebuilt from scratch. This is only supported when compiled with Berkeley DB support with transactions enabled. Trying recovery with QDBM or SQLite3 support will result in an error.</para> <para>The <option>--db-recover-harder <replaceable>dir</replaceable></option> option runs a catastrophic data base recovery in the specified database directory. If that fails, your database cannot be repaired and must be rebuilt from scratch. This is only supported when compiled with Berkeley DB support with transactions enabled. Trying recovery with QDBM or SQLite3 support will result in an error.</para> <para>The <option>--db-remove-environment <replaceable>directory</replaceable></option> option has no short option equivalent. It runs recovery in the given directory and then removes the database environment. Use this <emphasis>before</emphasis> upgrading to a new Berkeley DB version if the new version to be installed requires a log file format update.</para> <para>The <option>--db-print-leafpage-count <replaceable>file</replaceable></option> option prints the number of leaf pages in the database file <replaceable>file</replaceable> as a decimal number, or UNKNOWN if the database does not support querying this figure.</para> <para>The <option>--db-print-pagesize <replaceable>file</replaceable></option> option prints the size of a database page in <replaceable>file</replaceable> as a decimal number, or UNKNOWN for databases with variable page size or databases that do not allow a query of the database page size.</para> <para> The <option>--db-verify <replaceable>file</replaceable></option> option requests that <application>bogofilter</application> verifies the database file. It prints only errors, unless in verbose mode. </para> </refsect1> <refsect1 id="dataformat"> <title>DATA FORMAT</title> <para> <application>Bogoutil</application> reads and writes text files where each nonblank line consists of a word, any amount of horizontal whitespace, a numeric word count, more whitespace, and (optionally) a date in form YYYYMMDD. Blank lines are skipped. </para> </refsect1> <refsect1 id="returns"> <title>RETURN VALUES</title> <para> 0 for successful operation. 1 for most errors. 3 for I/O or other errors.
