NAME
prep − prepare text for statistical processing
SYNTAX
prep [ options ] file...
DESCRIPTION
The prep command reads each file in sequence and writes it on the standard output, one “word” to a line. A word is a string of alphabetic characters and embedded apostrophes, delimited by space or punctuation. Hyphenated words are broken apart. Hyphens at the end of lines are removed, and the hyphenated parts are joined. Strings of digits are discarded.
OPTIONS
−d Print the word number (in the input stream) with each word.
−i Take the next file as an “ignore” file. These words will not appear in the output. They will be counted, for purposes of the −d count.
−o Take the next file as an “only” file. Only these words will appear in the output. All other words will also be counted for the −d count.
−p Include punctuation marks (single nonalphanumeric characters) as separate output lines. The punctuation marks are not counted for the −d count.
Ignore and only files contain words, one per line.
