LOGIN_USER=root         ---預設值
LOGIN_PORT=3306         ---預設值
LOGIN_HOST=127.0.0.1    ---預設值

  2. parse_options "$@"
  echo "$LOGIN_USER $LOGIN_PASSWORD $LOGIN_PORT $LOGIN_HOST"
  1. if [ ! -n "$LOGIN_USER" ];then    
  2.      use_help
  3.      exit
  4. fi


  7. if [ ! -n "$LOGIN_PASSWORD" ];then
  8.      use_help
  9.      exit
  10. fi




  15. mysql -u$LOGIN_USER -p$LOGIN_PASSWORD -P$LOGIN_PORT -h$LOGIN_HOST -e "select now()"

使用辦法
[root@localhost python]# sh  goo.sh  --password=ESBecs00   
root ESBecs00 3306 127.0.0.1
