Of course, you should read the man page. O'Reilly has a pretty
good book on bash as well. Here are a few examples of what you want to
look for.

Yes. e.g. function:
function SayFoo
{
echo "Foo"
return 0
}
If you are doing menus, you should also consider using the
'select' command. It is designed to make menus simple to code up and
maintain.

Check out the 'trap' command. You can look at /etc/rc for some
examples of its use.

echo -n "Command >"
