From 4357569fdc7bc482dea0ef0bff57a70e7f06523c Mon Sep 17 00:00:00 2001 From: Ron Yorston Date: Sat, 21 Aug 2021 09:36:27 +0100 Subject: rev: correct output for long input lines The input buffer is initialised to a reasonable size and extended if necessary. When this happened the offset into the buffer wasn't reset to zero so subsequent lines were appended to the long line. Fix this and add some tests. function old new delta rev_main 377 368 -9 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-9) Total: -9 bytes Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko --- util-linux/rev.c | 1 + 1 file changed, 1 insertion(+) (limited to 'util-linux') diff --git a/util-linux/rev.c b/util-linux/rev.c index d439b4d..63b005c 100644 --- a/util-linux/rev.c +++ b/util-linux/rev.c @@ -109,6 +109,7 @@ int rev_main(int argc UNUSED_PARAM, char **argv) strrev(buf, strlen(buf)); #endif fputs_stdout(buf); + pos = 0; } fclose(fp); } while (*argv); -- cgit v1.1
