Linux 系統健康巡檢腳本

客戶應用系統服務器要做健康檢查，操作系統為Red Hat Enterprise Linux 5.6，數據庫為oracle 10g，寫了如下shell腳本：
#!/bin/bash
echo "You are logged in as `whoami`";
if [ `whoami` != root ]; then
echo "Must be logged on as root to run this script."
exit
fi
CHECK_DATE=`date +%F`
echo "Running script. at `date`"

ls -d $CHECK_REPORT_PATH
if [ $? -gt 0 ]
then
mkdir $CHECK_REPORT_PATH
