How to edit specific text files with linux terminal

Question

I don't know how to edit some text files and make my job easier. How can I get specific lines inside a enourmous text file, grab it and send to another text file (a new document).

Example 1:

>text_xyz

ASDFGHJKLJGDSAQWEERTYYGFS

.>text_abc

ASDFWQRTYGEQ

So, I need to find those terms (>text_xyz) and grab the lines under the title (ASDFGHJKLJGDSAQWEERTYYGFS).

I think this isn't a difficult job, because when I find the starting code ">" I just need to stop "grabing" when I find another code starting with ">" .

Then, I'll get only those lines:

**>text_xyz**

**ASDFGHJKLJGDSAQWEERTYYGFS**

How can I do this using Linux terminal?

i `grep` is the way to go also putting the grep in a shell script would make it portable and a lot easier. — jgr208, Oct 06 '14 at 13:45

But how do I set my text file as a "PATH" to the grep command? – aliochka Oct 06 '14 at 13:57
how do you tell it to look in the text file to grep or output? for information on the command run `man grep` – jgr208 Oct 06 '14 at 13:58
