NAME

     tricount - count trigrams


SYNOPSIS

     tricount [-v] [-i] [-b|-e] [-p number] -d trigrams [-f text]
     [-l level]


DESCRIPTION

     tricount counts the occurences of trigrams found in the file
     trigrams.   This  file must contain only ascii text one word
     per line in your favorite language. You will  need  to  pipe
     the output thru sort -r to get a nice listing.

     tricount uses the same tree structure as wordtree.


OPTIONS

     -d trigrams
          The argument  to  option  -d  is  the  file  containing
          strings where to extract or count trigrams from. If the
          -v option is given (count mode on), trigrams  are  pre-
          fixed  by  the  number  of  matches.  If this number is
          greater than zero the corresponding  trigram  has  been
          matched (n+1) times.

     -f text
          The argument  to  option  -f  is  the  file  containing
          strings to be classified if they contain the right tri-
          grams or not.

     -l level
          This option is only valid with -f. The argument is  the
          number  of occurences a trigram has to have in trigrams
          to be classified as a "proper" trigram.

     -i   invert mode. This flag has effect only if -f is  given.
          It  causes to print all strings from the file text that
          have trigrams listed in file trigrams.

     -b   begin. tricount will only count trigrams if  it  is  on
          the beginning of a string.  Furthermore if option -f is
          given tricount will  only  match  the  beginning  of  a
          string from text.

     -p number
          Changes  the  semantics  of  tricount  to  match  other
          lengths  of  pre-,  in-, or postfixes. For Example pen-
          tagrams are matched if number equals 5.

     -e   end. tricount will only count trigrams if it is on  the
          end  of  a  string.   Furthermore if option -f is given
          tricount will only match the trailer of a  string  from
          text.

     -v   be verbose.
