Top Forums Shell Programming and Scripting Grep word after last occurance of string and display next few lines Post 302879352 by nes on Thursday 12th of December 2013 04:56:26 AM

Hi MadeInGermany,

Following script is displaying from Last occurance "Starting" to end of file, but not searching ERROR/WARNING within that block.

Please guide me how to get next two lines with ERROR/WARNING within that block.

Code:
awk '  /ERROR|WARNING/ {if (cnt==0) s=s (s?RS:s) b; cnt=3}  cnt&&cnt-- {s=s RS $0}  /Starting/ {s=""; cnt=0}  {b=$0}  END {print s}' errorlog

---------- Post updated at 03:26 PM ---------- Previous update was at 02:59 PM ----------

when I have given following code it is displaying properly from last occurance 'Starting' to end of file, searching ERROR/WARNING and redirecting it in "Extractfile" also, but line number is displaying wrong in grep. Please advise me.

Code:
 
ERROR="ERROR"
WARNING="WARNING"
ERR=$ERROR"\|"$WARNING
ERRFILE="Extractfile"
 
awk '{if (cnt==0) s=s (s?RS:s) b; cnt=3}cnt&&cnt-- {s=s RS $0}/Starting/ {s=""; cnt=0}{b=$0}END {print s}' $file | grep -A3 -in "$ERR" >> $ERRFILE
