make && echo "hello" only print hello when make succeeds (kernel)

Question

For compiling the linux kernel, If I do

make_runner.sh && echo "hello"

it prints hello even if some of the kernel compilation fails.

Is there a way for it to only print if all of the compilation targets built correctly?

Where make_runner.sh is the following:

#!/usr/bin/env bash
set -xe
make O=out ARCH=arm64 CC=clang CLANG_TRIPLE=aarch64-linux-gnu- vendor/citrus-perf_defconfig
make O=out ARCH=arm64 CC=clang CLANG_TRIPLE=aarch64-linux-gnu- -j$(nproc --all) 2>&1 | tee kernel.log

Because of the pipe to tee, the second make’s exit status is ignored.

To get the behaviour you want, you need to enable pipefail: change the set -xe line to

set -xe -o pipefail

See Debugging scripts, what is the difference between -x to set -euxo pipefail? for details.

make && echo "hello" only print hello when make succeeds (kernel)
