PREP(1)
NAME
prep − prepare text for statistical processing
SYNOPSIS
prep [ −dio ] file ...
DESCRIPTION
Prep 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 imbedded 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.
The following option letters may appear in any order:
−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.
