Inserting multiline text from file to another file after pattern

Question

I have files like:

text2insert
filewithpattern

and also known:

pattern

How can i insert lines from text2insert into filewithpattern but after the pattern line?

Using bash 2.05b

UPDATE: Before filewithpattern should look like:

garbage
pattern1
pattern2
garbage

and after:

garbage
pattern1
text2insert lines
text2insert lines
text2insert lines
pattern2
garbage

Can you be more specific? Is the content after *pattern* deleted for example? — Eelvex, Feb 22 '11 at 01:04

It's wokring as i would like to. And it's short and simple. I like that very much. Thanks Dennis! – kasper Feb 22 '11 at 01:42
Is there a similiar script to insert the contents of `text2insert` *above* the line matched by `pattern`? – Frerich Raabe Oct 13 '12 at 20:14

awk 'FNR==NR{      a[c++]=$0;next     }
/pattern1/{g=1;next}
/pattern2/{g=0;next}
g{ 
  for(i=1;i<=c;i++){
    print a[i]
  }
}' text2insert filewithpattern

And why do you need "garbage" in your output? Your previous question seems not to include "garbage"

last line should be like this? i mean... what is the `file`?? – kasper Feb 22 '11 at 01:25
@kasper, `file` is `filewithpattern` – kurumi Feb 22 '11 at 01:28
well garbage was just to make a point that there is something before and aftern pattern that shouldn't be touched by the script. – kasper Feb 22 '11 at 01:42
