choose CASE on shell

如果在一个OS下面创建多个实例，那么在今天这个OS的时候profile的设定该怎么选择呢？

在profile中加入以下内容:

 

#!/usr/bin/ksh
JOBFLG=

MENU()
{
clear
echo ""
echo "*TOP MENU"
echo "-------------------------------------------------"
echo "    TEST DB : Please choose which DB    "
echo "-------------------------------------------------"
echo " "
echo "     A. XXXX"
echo " "
echo "     B. YYYY"
echo " "
echo "-------------------------------------------------"
echo "     Q. quit"
echo "-------------------------------------------------"
echo "     Select Job => \c  "
read JOBFLG
}

while MENU
do

    case "$JOBFLG" in
    [Aa])
            . ~xxxxx/../xxxxx_profile
            ## exit 1 -- exit still on root ; break -- already go into user

            break
            ;;
    [Bb])
            . ~yyyyy/../yyyyy_profile
            break 
            ;;
    [Qq])
            echo " "
            echo "O.K :Good bye !!"
            echo " "
            exit 1
            ;;
    esac
done

 

这样一来进入OS的时候会提示要进入那一个instance就不会盲目了。不同instance的profile弄个不同的吧
