Insert content of a file right after pattern in another file
suppose i have original file:

Code:
original.txt:

hello
how are you
you are wonderful
what time is it
I went to the store last night. and some apple juice


then i have another file:

Code:
anotherfile.txt:

with my friends mary, john and harry.
We had a great time.
We bought food

Suppose i want to add the content of anotherfile.txt right after the pattern "last night".

so the resulting output looks like this:

Code:
hello
how are you
you are wonderful
what time is it
I went to the store last night with my friends mary, john and harry.
We had a great time.
We bought food and some apple juice

I'd like to use awk for this. and the awk code i'm attempting to use is this:

Code:
awk '/last.*night/{printf $0; while(getline line<"anotherfile.txt"){print line};next}1' originalfile.txt > resultingfile.txt

for some reason, when i run the above command, it doesn't do anything. it just outputs the original file to resultingfile.txt
