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.  Hyphented 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.
