You have a log file which has lines around 30k. There is another file which has some error pattern(like invalid_request, no_file etc). Now, write a program (in perl/shell)which will output the log and its previous/next 5 lines. Ex: If the pattern(like no_file) occurs at line 200, then lines from 195 to 205 (11 lines) should be added to the output file.
