Reporting lines above a particular pattern
Below is a typical report
each of the lines represent the fields in the report

Code:
component1
component2
<pattern>
..
..
n lines ...
..
VIOL       = 2

the command should display
Code:
component1
component2
VIOL       = 2

only if pattern field of the report is "good"

component1 and component 2 will be always in the lines preceding the <pattern> field and the VIOL pattern is after n lines..
Please help

Hi itkamaraj,

INPUT FILE is
Code:
 Startpoint: ff1
               (rising edge-triggered flip-flop clocked by CLK3)
 Endpoint: ff4
               (rising clock gating-check end-point clocked by CLK4)
  Path Group: good
  Path Type: min
  Point                                                                                                                  
  ----------------------------------
  clock CLK1 (rise edge)                                                                                       
  clock network delay (propagated)      
VIOL   =  10

OUTPUT is (as the path group field is good...as mentioned earlier ...if the path group field is any pattern other than good it should not display anything)
Code:
 Startpoint: ff1
               (rising edge-triggered flip-flop clocked by CLK3)
 Endpoint: ff4
               (rising clock gating-check end-point clocked by CLK4)
 VIOL   =  10

Code:
 
$ awk '/Path.*good/{a=1}!a{line=line"\n"$0}/VIOL/{if(a){print line"\n"$0}}' input.txt
Startpoint: ff1
(rising edge-triggered flip-flop clocked by CLK3)
Endpoint: ff4
(rising clock gating-check end-point clocked by CLK4)
VIOL = 10

Please tell me how its working...
also will this work if there are multiple reports in a file say
Code:
Startpoint: ff1
               (rising edge-triggered flip-flop clocked by CLK3)
 Endpoint: ff4
               (rising clock gating-check end-point clocked by CLK4)
  Path Group: good
  Path Type: min
  Point                                                                                                                  
  ----------------------------------
  clock CLK1 (rise edge)                                                                                       
  clock network delay (propagated)      
VIOL   =  10              



Startpoint: ff5
               (rising edge-triggered flip-flop clocked by CLK6)
 Endpoint: ff7
               (rising clock gating-check end-point clocked by CLK40)
  Path Group: bad
  Path Type: min
  Point                                                                                                                  
  ----------------------------------
  clock CLK1 (rise edge)                                                                                       
  clock network delay (propagated)      
test
VIOL   =  15              




Startpoint: ff90
               (rising edge-triggered flip-flop clocked by CLK3f
 Endpoint: ff46
               (rising clock gating-check end-point clocked by CLK4f)
  Path Group: good
  Path Type: min
  Point                                                                                                                  
  ----------------------------------
  clock CLK1 (rise edge)                                                                                       
  clock network delay (propagated)      
VIOL   =  105





output should be
Code:
Startpoint: ff1
                (rising edge-triggered flip-flop clocked by CLK3)
  Endpoint: ff4
                (rising clock gating-check end-point clocked by CLK4)
VIOL   =  10              
Startpoint: ff90
                (rising edge-triggered flip-flop clocked by CLK3f
  Endpoint: ff46
                (rising clock gating-check end-point clocked by CLK4f)
VIOL   =  105

Please give any alternate command to do the same
.......

Why not try it yourself and see?

In the future, please be considerate of those who decide to volunteer some of their time to help you by providing representative sample input and output data, and stating all the conditions and special cases in your original problem statement. Otherwise, someone will squander their time and expertise on a solution that, due to subsequently-disclosed requirements, will either require refinement or abandonment. This goes both ways; you will also save yourself some time, by not having to post multiple followups requesting further functionality or responding to requests for clarification.

Reporting lines above a particular pattern
Hi Itkamraj,

I still need to understanding this logic, if you donot mind.

Code:
 
awk '/Path.*good/{a=1}!a{line=line"\n"$0}/VIOL/{if(a){print line"\n"$0}}' input.txt
