Start/Shutdown of Oracle Databases in Unix

Does anyone have any unix shell scripts to startup and shutdown multiple databases in unix. i have to do the following manually and it gets boring every time.

1. su - oracle
2. set environment variables (ORACLE_SID is the one that will need to change each time i need to startup a differnet database.
3. sqldba lmode=y inside the sqldba i then type
4. connect internal
5. startup or shutdown immediate 6 . exit

I have to repeat that process each time for every database on the server. how can i make it automatically in a shell script do all of those things without the need for user intervention. i want to start and stop it from cron as well. I need it to be able to change to a different database name each time and be able to start or stop all or some of them.

We are running on Sun OS 5.4/Solaris 2.4
