shell cmd to search for an item and print 3 lines 1

[marrow]

I have a large logfile (Solaris 2.6) and am searching for an occurrance of an IP address and then want to print that address plus the next 3 lines. I could simply more it but I'd like to do it in a script. I beleive "sed" might achieve this or is nawk better. Examples appreciated.

Hi marrow. Quick and dirty way would be ...

awk '/w.x.y.z/ {print;getline;print;getline;print;getline;print;}' log_file

Just put the correct IP address as the pattern to match.

Greg.
