Try and adapt the following awk program.
steve.awk :
Code:
{
   if (match($0, /\[/) == 0) {
      Lines[++LinesCount] = $0;
      LineIds[LinesCount] = ""
      next;
   }

   id  = substr($0, RSTART);

   if (++Ids[id] == 1) {
      Lines[++LinesCount] = $0;
      LineIds[LinesCount] = id;
   }
}

END {
   for (i=1; i<=LinesCount; i++) {
      print Lines[i];
      if (id = LineIds[i]) {
         if (Ids[id] > 1) {
            print "This Error was reproduced", Ids[id], "times";
         }
      }
   }
}

Execute the awk program :
Code:
awk -f steve.awk logreport

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
