file A

aa  22  48
ab 22  48
tcf 50 76
gf 50 76
h  89  100
yh 89   100

how can we split the file on the basis of common 2 and third column
output like

file A-1
aa  22  48
ab 22  48

file A-2
cf  50  76
gf  50   76

file A-3
th  89  100
yh 89   100
2 
$> awk '$2==a && $3==b {print; next} {i++; if(NR==1){print "file A-"i}else{print "\nfile A-"i}; a=$2; b=$3; print}' infile
file A-1
aa  22  48
ab 22  48

file A-2
tcf 50 76
gf 50 76

file A-3
h  89  100
yh 89   100

I don't like spaces in file names so I added an underscore:

awk '$2==a && $3==b {print >> "file_A-"i; next} {i++; a=$2; b=$3; print >> "file_A-"i}' infile
