From e4655963c25e7b6c4ab22a095e04c7cd3de61b0b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Fr=C3=A9d=C3=A9ric=20G=2E=20MARAND?= Date: Sat, 9 Jul 2022 22:33:23 +0200 Subject: Update awk.html.markdown The `gsub` example is incorrect: with pattern `"e+"`, one gets `"m.t m. at th. bar"`. To get `"m..t m. at th. bar"` as documented, the pattern is just `"e"`. Otherwise we could keep "e+" but change the result. Also removed an extra dot at the end of a sentence. --- awk.html.markdown | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'awk.html.markdown') diff --git a/awk.html.markdown b/awk.html.markdown index 3ff3f937..b8b6271a 100644 --- a/awk.html.markdown +++ b/awk.html.markdown @@ -48,7 +48,7 @@ BEGIN { # the preliminary set-up code, before you process any text files.
