i dont think i understood that correctly. Please check my code to see if this is what you meant. by the way, thank you very much for helping me. i was out of options.

Code:
 file=../data/globallyIgnoredTc.dat
   #set -A ignore `grep -v "#" ${file} | tr '[A-Z]' '[a-z]' `
   set -A ignore `grep -v "#" ${file} `
   ign=${ignore[@]}
       #################################################

  endMarker="NSC Termination Event Details:"

  if [ ! -f $4 ] ; then
    echo "No $4 file found.  Perhaps testMgr is still running?"

  else

    # Subtract out a little from the start time.  Otherwise we miss
    # crashes because of the controller clocks being off by a few seconds.
    #dateFilter $4 $(( $2 - 10 )) $3 > $con

    # BGL -- analyze all of the consoles.  Autotest does the trimming now.
    
	if [ $(print - "${ignore[@]}" | grep -c "$2") -gt 0 ] ; 
		then 
			status="found $2 in array ignore[]" 
		else 
			status="did not find $2 in array ignore[]" 
	fi



    termReport.pl < $4 | dos2ux |  head -2000 | awk '
    
    BEGIN { foundTermEvent=0;
            endMarker="'"${endMarker}"'"; }

    {
      if ( (substr($0, 1, length(endMarker)) == endMarker) ||
           (substr($0, 1, 39) == "'${SBINDIR}'/termReport.pl: ") )
      {
        if (foundTermEvent == 1)
        {
          print "";
          foundTermEvent=0;
        }
      }
      ##############################################################################
       if (foundTermEvent == 1)
       {
				  if (status == "found $2 in array ignore[]")
				  {
                  foundTermEvent = 0;
				  }

                  else
                  {
				  print;
				  }
   

       }

      if (substr($0, 1, 18) == "Termination Event:")

You are right. Did the script run fine now?

i dont get any errors now. but it is not doing what it supposed to do. it seems like it never finds a match when comparing $2 to the array. in reality, there are matches and it should find it.

could this happen because we have if statement before i have any data for $2?

---------- Post updated at 01:04 PM ---------- Previous update was at 12:46 PM ----------

i verified this, it doesnt have correct values for $2 by the time if statement excuted. Because $2 values arent going to be ready till AWK statemnet has been excuted.

Is $2 second argument to your script or Second field in your input from termReport.pl?
# 19  
Old 04-21-2010
$2 is comming from termReport.pl out put. it is the 2nd field.
# 20

Create another script to check whether second field exists in ignore array

checkSecondFldInArray
Code:
file="path_to_file"
set -A ignore `grep -v "#" ${file} ` 

if [ $(print - "${ignore[@]}" | grep -c "$1") -gt 0 ] ; 
then 
	echo "found" 
else 
	echo "not found" 
fi

Change awk code to call above script
Code:
if (foundTermEvent == 1) 
{ 
	"checkSecondFldInArray " $2 | getline status
	if (status == "found") { foundTermEvent = 0; }

array "ignore" reads a data file. data file only has a one field and i verfied that ignore arrray loads with correct info as follows.
ignore[0]=erf45
ignore[1]=34fgh
.
.
ignore[n]=rtghf

$2 comes from termReport.pl output. It seems like $2 doesnt get read before we use it. Does this make sense?

in the if statement, i tried to print the value for $2 so i can see if it get correct value. but it does not. please see the code below




Code:
. lib.ksh

if [ _$1  = _-all ] ; then
  all=1
fi  

failures=/tmp/failures.tmp
failLines=/tmp/failLines.tmp
utilFailLines=/tmp/utilFailLines.tmp
miscompareLines=/tmp/miscompareLines.tmp
con=/tmp/con.tmp
failInfo=/tmp/failInfo.tmp

function analyzeConsole
{
  # First, cut the console data down to just the part that printed
  # out during that test.  
  # Then run it through termReport.pl.
  # Then get the interesting parts of that.
