Linux安全中系统文件-系统core dump状态的方法以及演示过程是什么？

echo "SBL-Linux-04-01-01:" >> "/tmp/${ipadd}_checkResult.txt"
limitsFile=$(cat /etc/security/limits.conf | grep -V ^# | grep core)
if [ $? -eq 0 ];then
  soft=`cat /etc/security/limits.conf | grep -V ^# | grep core | awk {print $2}`
  for i in $soft
  do
    if [ "$i"x = "soft"x ];then
      echo "Y:* soft core 0 已经设置" >> "/tmp/${ipadd}_checkResult.txt"
    fi
    if [ "$i"x = "hard"x ];then
      echo "Y:* hard core 0 已经设置" >> "/tmp/${ipadd}_checkResult.txt"
    fi
  done
else 
  echo "N:没有设置core，建议在/etc/security/limits.conf中添加* soft core 0和* hard core 0" >> "/tmp/${ipadd}_checkResult.txt"
fi
