set -f
a=$(ps -eo args 2>/dev/null | grep -E '^([^ ]*/)?etcd( |$)' | head -n 1)
[ -n "$a" ] || a=$(cat /etc/kubernetes/manifests/etcd.yaml 2>/dev/null | tr '\n' ' ')
d=$(printf '%s\n' "$a" | tr ' "' '\n\n' | sed -n 's/^--data-dir=//p' | tail -n 1); d=${d:-/var/lib/etcd}
[ -d "$d" ] || exit 1
o=$(stat -Lc %U:%G "$d") || exit 1
if [ "$o" = "etcd:etcd" ]; then echo compliant; else echo "noncompliant: $d $o"; fi

预期输出: compliant
