I have an input file which contains so many entries like this: And, I want to count hw many among ASN in one column are converted to LYS in third coulmns. which means output shuld contain only "ASN number LYS"

Kindly let me know wny programm for this

My input is

Code:

VAL 156 MET 
THR 254 ILE 
GLY 153 SER 
SER 269 ILE 
VAL 249 PHE 
VAL 285 ILE 
PHE 233 VAL 
PHE 256 LEU 
VAL 132 LEU

I want output shuld contain all series of different numbers but same ASN and LYS in one row.

ASN number LYS

Code:

grep 'ASN [0-9]* LYS' inputfile

To get the count, use grep's -c switch.
