[PATCH] selftests: make shell scripts POSIX-compliant
From: Aditya Dutt <hidden>
Date: 2025-02-16 12:02:36
Also in:
cgroups, linux-kernel-mentees, linuxppc-dev, lkml
Subsystem:
control group (cgroup), kernel selftest framework, networking [general], the rest · Maintainers:
Tejun Heo, Johannes Weiner, Michal Koutný, Shuah Khan, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
Changes include: - Replaced [[ ... ]] with [ ... ] - Replaced == with = - Replaced printf -v with cur=$(printf ...). - Replaced echo -e with printf "%b\n" ... The above mentioned are Bash/GNU extensions and are not part of POSIX. Using shells like dash or non-GNU coreutils may produce errors. They have been replaced with POSIX-compatible alternatives. Signed-off-by: Aditya Dutt <redacted> --- I have made sure to only change the files that specifically have the /bin/sh shebang. I have referred to https://mywiki.wooledge.org/Bashism for information on what is and what isn't POSIX-compliant. tools/testing/selftests/cgroup/test_cpuset_v1_hp.sh | 10 +++++----- tools/testing/selftests/kexec/kexec_common_lib.sh | 2 +- tools/testing/selftests/kexec/test_kexec_file_load.sh | 2 +- tools/testing/selftests/net/veth.sh | 10 +++++----- tools/testing/selftests/powerpc/eeh/eeh-vf-aware.sh | 2 +- tools/testing/selftests/zram/zram_lib.sh | 2 +- 6 files changed, 14 insertions(+), 14 deletions(-)
