Hello beca123456,

Sorry for confusion, could you please try this following with same concept and little editing with conditions.
Code:
awk -F"|" 'FNR==NR{i=0;{if($1 ~ /Ref/){next};X[$2]=$1>3?X[$2]+1:X[$2]+0;next}}; {A=$2;{if(X[A] >= 1 && $1=="Ref"){;print $0} else if(X[A] < 1 && $1=="Ref"){$0=$0 OFS "*";print $0} else {print $0}}}' OFS="|"  Input_file Input_file

Let's say we have 2 senarios as follows.
Code:
cat test17
3|Bob
1|Bob
Ref|Bob
2|Rick
3|Rick
Ref|Rick
 
awk -F"|" 'FNR==NR{i=0;{if($1 ~ /Ref/){next};X[$2]=$1>3?X[$2]+1:X[$2]+0;next}}; {A=$2;{if(X[A] >= 1 && $1=="Ref"){;print $0} else if(X[A] < 1 && $1=="Ref"){$0=$0 OFS "*";print $0} else {print $0}}}' OFS="|"  test17 test17
 
3|Bob
1|Bob
Ref|Bob|*
2|Rick
3|Rick
Ref|Rick|*

2nd senario:
Code:
cat test17
4|Bob
1|Bob
Ref|Bob
2|Rick
4|Rick
Ref|Rick
 
 
awk -F"|" 'FNR==NR{i=0;{if($1 ~ /Ref/){next};X[$2]=$1>3?X[$2]+1:X[$2]+0;next}}; {A=$2;{if(X[A] >= 1 && $1=="Ref"){;print $0} else if(X[A] < 1 && $1=="Ref"){$0=$0 OFS "*";print $0} else {print $0}}}' OFS="|"  test17 test17
 
4|Bob
1|Bob
Ref|Bob
2|Rick
4|Rick
Ref|Rick

EDIT: Adding a non oneliner solution for same.
Code:
awk -F"|" 'FNR==NR      {
                                i=0;
                        {
                                if($1 ~ /Ref/)
                                                {
                                                        next
                                                };
                                X[$2]=$1>3?X[$2]+1:X[$2]+0;next
                        }
                        };
                        {
                                A=$2;
                        {
                                if(X[A] >= 1 && $1=="Ref")
                                                {
                                                        print $0
                                                }
                                else if(X[A] < 1 && $1=="Ref")
                                                {
                                                        $0=$0 OFS "*";
                                                        print $0
                                                }
                                else
                                                {
                                                        print $0
                                                }
                        }
                        }
           ' OFS="|" test17 test17


Thanks,
R. Singh
