AIX 健康检查脚本
各位 大神，请解释一下脚本都是什么意思？
RC=0
unset result
result=`uptime | grep days | awk '{print $3}'`
if [ ! -z "${result}" ] ; then
if [ ${result} -gt 8000 ] ; then
echo "System is up over 8000 days; this is a sign of a corrupt /etc/utmp file."
RC=1
fi
fi
if [ ${RC} -eq 0 ] ; then
result=`who -r`
if [ -z "${result}" ] ; then
echo "Unable to determine run-level with the who -r command."
echo "This is a sign of a corrupt /etc/utmp file."
RC=1
fi
fi
return ${RC}
RC=0
unset result
result=`uptime | grep days | awk '{print $3}'`
if [ ! -z "${result}" ] ; then
if [ ${result} -gt 8000 ] ; then
echo "System is up over 8000 days; this is a sign of a corrupt /etc/utmp file."
RC=1
fi
fi
if [ ${RC} -eq 0 ] ; then
result=`who -r`
if [ -z "${result}" ] ; then
echo "Unable to determine run-level with the who -r command."
echo "This is a sign of a corrupt /etc/utmp file."
RC=1

fi
return ${RC}

前段是检测系统已经运行了8000天以上，就显示提示【System is up over 8000 days; this is a sign of a corrupt /etc/utmp file.】，结束脚本，并且返回值为1.
后一段是前一段测试如果不大于8000天（返回值等于0时），检测当前进程的运行级别，如果结果为空（result的值为空），就显示提示信息【Unable to determine run-level with the who -r command.】【echo "This is a sign of a corrupt /etc/utmp file.】，结束脚本，并且返回值为1.收起
