Delete text in file using bash script in CentOS

Question

I'm a student from indonesia and I want to create an script that deletes few lines from a file containing the following text:

zone "irf.com" {
type master;
file "db.irf.com";
allow-update { none; };
};

zone "friedrice.com" {
type master;
file "db.friedrice.com";
allow-update { none; };
};

zone "you.com" {
type master;
file "db.you.com";
allow-update { none; };
};

If i want to delete this:

zone "friedrice.com" {
type master;
file "db.friedrice.com";
allow-update { none; };
};

In the terminal I can run: sh you.txt friedrice

How is the syntax in shell programming??

All the text is in a file, let's say you.txt

I'm a newbie, so please help me
