You need to retain the output until the end and reset it at every match.
Here is a sample code, though not very elegant:
Code:
nawk 'c-->0{res=sprintf("%s%s\n",res,$0)};$0~s{res="";if(b)for(c=b+1;c>1;c--)res=sprintf("%s%s\n",res,r[(NR-c+1)%b]);res=sprintf("%s%s\n",res,$0);c=a}b{r[NR%b]=$0}END{printf("%s",res)}' b=2   a=4 s="There is no process to read data written to a pipe" File.log

NAME
viewlores - display elements of a lores_list ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in Paris, France. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.fr SYNOPSYS
#include "mlo.h" void viewlores(ptres) lores_list *ptres ; PARAMETER
ptres Pointer to the lores to be scaned DESCRIPTION
viewlores scans all the primary elements of the lores_list loaded in ram, and displays a textual output of the data strcuture contents. Its use is mostly for debugging purposes, and educational ones, since the output is quite verbose, even if very easy to understand. EXAMPLE
#include <stdio.h> #include "mlo.h" void view_res(lofig_list *ptfig) { lores_list *res = NULL ; for(res = ptfig -> LORES ; res != NULL ; res = res -> NEXT) { viewlores(res) ; } } SEE ALSO
