Linux指令碼
客戶應用系統伺服器要做健康檢查，作業系統為Red Hat Enterprise Linux 5.6，資料庫為oracle 10g，寫了如下shell指令碼：
  1. #!/bin/bash
  3. echo "You are logged in as `whoami`";
  5. if [ `whoami` != root ]; then
  7. echo "Must be logged on as root to run this script."
  9. exit
  11. fi
  13. CHECK_DATE=`date +%F`
  15. echo "Running script. at `date`"
  17. CHECK_REPORT_PATH=/tmp/getinfo
  19. ls -d $CHECK_REPORT_PATH
  21. if [ $? -gt 0 ]
  23. then
  25. mkdir $CHECK_REPORT_PATH
  27. fi
  29. chmod -R 777 $CHECK_REPORT_PATH
  31. CURRENT_DIR=`pwd`
  33. echo "#################### Check Start ####################"
  35. HOST=`hostname`
  37. echo "********Hostname Check**********" >$CHECK_REPORT_PATH/Report_$CHECK_DATE
