From 90d132ee44b76350e4aebd36b7598d425b25c996 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sat, 18 Dec 2021 23:16:38 -0500 Subject: [PATCH] common/filter: add _filter_bash() This is needed to account for bash 5.1 adding line number annotation when executing a command via the -c option and it fails. For example, "bash -c 'echo foo > /'" will cause bash 5.1 to report: bash: line 1: /: Is a directory instead of: bash: /: Is a directory Signed-off-by: Theodore Ts'o Reviewed-by: Eric Biggers Signed-off-by: Eryu Guan --- common/filter | 11 +++++++++++ tests/generic/572 | 33 +++++++++++++++++++-------------- 2 files changed, 30 insertions(+), 14 deletions(-) diff --git a/common/filter b/common/filter index 2efbbd99..c3db7a56 100644 --- a/common/filter +++ b/common/filter @@ -661,5 +661,16 @@ _filter_quota_report() s|^(.*?)
