Sample cold backup script

I am new to oracle backup. Can someone show me how to write unix shell script to do a cold backup?

I would like to do the following:

1. Prompt the user to select an option.
2. Say option 2 is to do cold backup.
3. Connect to db to get datafiles, control files, redolog files' names.
4. Shutdown db.
5. Send the files' name to a file.
6. Perform tar -cvf of the files' name.
7. Startup db.
8. Show option again.

Thanks,
