bogoutil [options] {-d | -l | -m | -w | -p} file.db
        

bogoutil {-r | -R} directory

bogoutil {-h | -V}

where options is

 [-n] [-D] [-a age] [-c count] [-s min,max] [-y date]
 [-I file] [-x flags]

 

DESCRIPTION

Bogoutil is part of the bogofilter Bayesian spam filter package.

It is used to dump and load bogofilter's Berkeley DB databases to and from text files, perform database maintenance functions, and to display the values for specific words.

 

OPTIONS

The -d option tells bogoutil to print the contents of the specified database file to stdout.

The -l option tells bogoutil to load the data from stdin into the specified database file.

The -m option tells bogoutil 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.

The -w option tells bogoutil to display the value of one or more tokens in one or more databases. -w takes an argument, which is either the name of a wordlist or the name of a directory containing spamlist.db and goodlist.db. Tokens can be listed on the command line or piped to bogoutil. When there are extra arguments on the command line, bogoutil will use them as the tokens to lookup. If there are no extra arguments, bogoutil will read tokens from stdin. When file.db is the path to a database file, the tokens will be looked up in the database and the value for each token will be displayed. When file.db is a directory name, each token will be looked up in both spamlist.db and goodlist.db and the values will be displayed.

The -p option tells bogoutil to display the value of one or more tokens in one or more databases and add a column of probabilities to the output. Option -p takes the same arguments as option -w .

The -r option tells bogoutil to recalculate the ROBX value and print it as a six-digit fraction.

The -R option does the same as -R, but prints more information and saves the result in the training database.

The -I file option tells bogoutil to read its input from file rather than stdin.

The -v option produces verbose output on stderr. This option is primarily useful for debugging.

The -D redirects debug output to stdout (it usually goes to stderr).

The -x flags option sets debugging flags.

Option -n 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 '-m' or '-l', but not with '-d'.

Option -a age 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 age days.

Option -c value indicates that tokens with counts less than or equal to value are to be discarded.

Option -s min,max is used to discard tokens based on their size, i.e. length. All tokens shorter than min or longer than max will be discarded.

Option -y date is specifies the date to give to tokens that don't have dates.

The -h option prints the help message and exits.

The -V option prints the version number and exits.

 

DATA FORMAT


 Bogoutil 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.

 

RETURN VALUES

0 for successful operation. 1 for most errors. 2 for I/O or other errors. Error 2 usually means that something is seriously wrong with the database files.
