Hmmm....

  grep av: *.db.save | awk '{print $2;}' | sort | uniq -c | sort -n
     1 AS2551
     1 AS3819
     1 AS4690
     1 AS6113
     1 AS6461
     1 AS6467
     1 AS93
     2 AS4200
     2 AS6151
     3 AS3491
     7 AS668
     8 AS1800
     8 AS6076
    12 AS6122
    64 AS3561
    70 AS1239
   186 AS1275
  60957 AS690
