awk shell scripting

Comment:

is it possible with awk or grep (or some other unix tool) to stop the search of a text file after the number of results reaches a predifined number. I am searching rather large files and would only like to capture the first 2000 or so results. Thus for speed resons i would like awk or grep to brake out of the loop when 2000 results are recieved. any suggestions would be very helpful thanks -evan

With awk you can do something like this : awk '/search_pattern/ { print ; if (--count == 0) exit }' count=2000 input_file Jean-Pierre.
