Shell Programming and Scripting

Dear experts,

Im trying to create a script which will allow me to do the following:

1) log in with a username and password.

2) select an option.

this is how the menu looks:

Select one of the following options:

1 - Activation Menu
2 - Troubleshooting Menu
3 - New Window
4 - Database Creation
5 - Database Maintenance

q - Quit

Enter option number --->

Any good suggestions/ links where i can get a headstart?

Thanks.

        clear
        echo Menu:
        echo 1 - Activation Menu
        echo 2 - Troubleshooting Menu
        echo 3 - New Window
        echo 4 - Database Creation
        echo 5 - Database Maintenance
        echo
        echo q - Quit
        echo
        echo -n Please enter your option:
        read CHOSEN_KEY
        case $CHOSEN_KEY in
                1)      echo You chose 1
                        break;;
                2)      echo You chose 2
                        break;;
                3)      echo You chose 3
                        break;;
                4)      echo You chose 4
                        break;;
                5)      echo You chose 5
                        break;;
                q)      echo Bye bye
                        exit;;
        esac
done

hi fongthai,

many thanks for the help but this is not what i want. maybe i did not phase myself clearly.

the menu has been created and been running fine.

right now im trying to write a script where i can call this menu up and make the selection.

reason being some of the services may not be runningi fine so i need to monitor and activate those service in time when they are down.

thanks again.

hi,

may I suggest you have a while loop script which does a several checks and assign these values to flatfiles. Then followed by 'if' or case conditions which test against these flastfiles. Finally su - someuser whose .profile is modified to fireoff some script.

I have a similiar script but not 'case' which I run nohup'd on my boxes which wakes up every 300 seconds or 5mins to run these tests. If test condition confirms any dead process it will su - "bouncer", a user on my box which has a modified .profile to restart all my apps in proper sequence, otherwise it justs sends email alerts or do nothing just logging to nohup.out. Maybe u can modify it for your purpose.

good luck
