That's because you dropped the header line.

---------- Post updated at 14:21 ---------- Previous update was at 14:20 ----------

Output with header line in file:
Code:
Column1    Column2    Column3    Column4    Column5    Column6    Column7
3    user1    access1    word    word    3    1
2    user2    access2    word    word    5    3

Hi,

Once again thanks for your help. It seems that it works with:

Code:
Column1    Column2    Column3    Column4    Column5    Column6    Column7
1    user1    access1    word    word    3    2
2    user2    access2    word    word    5    3
3    user1    access1    word    word    3    1
4    user1    access2    word    word    2    1
5       user1    access2    word    word    2    1

but not with

Code:
Column1    Column2    Column3    Column4    Column5    Column6    Column7
1    user1    access1    word    word    3    2
2    user2    access2    word    word    5    3
3    user1    access1    word    word    3    1
4    user1    access2    word    word    2    1

Moreover, is it possible not to include the header line in the results?

Thanks

Well, I've noticed that as well. Try
Code:
awk '
NR==1           {# print
                 next
                }

                {LINE[$2,$3]=$0
                 FREQ[$2,$3]++
                 SUM[$2,$3]=$6+$7
                 if (FREQ[$2,$3] == MAX[$2])    if (SUM[$2,$3]  < MIN[$2]) MIN[$2] = SUM[$2,$3]
                 if (FREQ[$2,$3] >  MAX[$2])    {MAX[$2] = FREQ[$2,$3]
                                                 MIN[$2] = SUM[$2,$3]
                                                }
                }
END             {for (f in FREQ)        {split (f, TMP, SUBSEP)
                                         if     (FREQ[f] == MAX[TMP[1]] &&
                                                 SUM[f] == MIN[TMP[1]])
                                            print LINE[f]
                                        }
                }
' FS="\t" SUBSEP="\t" file
