This line of awk code does two things:
- Look in the current input line ($0) for a sentence starting with The broker followed by one character that is not a period ([^.]) followed by zero or more characters that are not periods ([^.]*) followed by a period ([.]).
- Print the 1st input field followed by the output field separator (aka OFS) ($1,, the 2nd field followed by the OFS ($2,), the 3rd field followed by a colon followed by the OFS ($3 ":",) followed by the sentence found by the match() function if a sentence was found or an empty string if no sentence was found(substr($0, RSTART, RLENGTH)).

STYLE(1) General Commands Manual STYLE(1)
NAME
style - analyze surface characteristics of a document
SYNOPSIS
style [ -ml ] [ -mm ] [ -a ] [ -e ] [ -l num ] [ -r num ] [ -p ] [ -P ] file ...
DESCRIPTION
Style analyzes the surface characteristics of the writing style of a document. It reports on readability, sentence length and structure,
word length and usage, verb type, and sentence openers. Because style runs deroff before looking at the text, formatting header files
should be included as part of the input. The default macro package -ms may be overridden with the flag -mm. The flag -ml, which causes
deroff to skip lists, should be used if the document contains many lists of non-sentences. The other options are used to locate sentences
with certain characteristics.
-a print all sentences with their length and readability index.
-e print all sentences that begin with an expletive.
-p print all sentences that contain a passive verb.
-lnum print all sentences longer than num.
-rnum print all sentences whose readability index is greater than num.
-P print parts of speech of the words in the document.
SEE ALSO
deroff(1), diction(1)
BUGS
Use of non-standard formatting macros may cause incorrect sentence breaks.
