I have not tried Paul's posted script, but it does point out a
possible confusion/unclarity in Paul's request. it looks to me
that Paul's script will _only_ print matches when word1 is at
the end of a line and word2 is at the start of the next line.
(it also does not allow trailing spaces at the end of line 1
or leading spaces on line 2, both of which are legal and
harmless in (La)TeX.)
but that is not how I read Paul's question. I read it as wanting
to print something (nominally each line) that "matches", where a
match is word1, whitespace (including up to one newline), then
word2. e.g., the single line “foo word1 word2 bar” would also
match — which is not printed by Paul's gawk(1) solution.
