extract lines from text after keyword
I have a text and I want to extract the 4 lines following a keyword!

For example if I have this text and the keyword is AAA

Code:
hello
helloo
AAA
one
two
three
four
helloooo
hellooo

I want the output to be
Code:
one
two 
three 
four

if your grep supports -A option, then use it like

Code:
grep -A 4 "AAA" file.txt

else, you can try with awk

Code:
awk '/AAA/{for(i=1;i<=4;i++){getline;print}exit;}' file.txt

Try:
Code:
awk 'p-->0; /AAA/{p=c}' c=4 infile
