To avoid this issue, use printf which handles escape characters as a standard feature and is more widespread among modern shells. The output is now formatted as expected (x86 build this time): Emit Tests for alsa Emit Tests for amd-pstate Skipping non-existent dir: arm64 Reported-by: "kernelci.org bot" Suggested-by: David Laight Fixes: 3297a4df805d ("kselftests: Enable the echo command to print newlines in Makefile") Signed-off-by: Guillaume Tucker --- Notes: v2: use printf insead of $(which echo) tools/testing/selftests/Makefile | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tools/testing/selftests/Makefile b/tools/testing/selftests/Makefile index 41b649452560..06578963f4f1 100644 --- a/tools/testing/selftests/Makefile +++ b/tools/testing/selftests/Makefile @@ -236,8 +236,8 @@ ifdef INSTALL_PATH @# included in the generated runlist. for TARGET in $(TARGETS); do \ BUILD_TARGET=$$BUILD/$$TARGET; \ - [ ! -d $(INSTALL_PATH)/$$TARGET ] && echo "Skipping non-existent dir: $$TARGET" && continue; \ - echo -ne "Emit Tests for $$TARGET\n"; \ + [ ! -d $(INSTALL_PATH)/$$TARGET ] && printf "Skipping non-existent dir: $$TARGET\n" && continue; \ + printf "Emit Tests for $$TARGET\n"; \ $(MAKE) -s --no-print-directory OUTPUT=$$BUILD_TARGET COLLECTION=$$TARGET \ -C $$TARGET emit_tests >> $(TEST_LIST); \ done; -- 2.30.2
