Hello,
I have a string below
DUMMY=1,2,3,4,5,6
I want to extract fields 1-3 and put it as under in a file
1,2,3
I can do this using cut like below
echo $DUMMY | cut -d, -f1-3
But I would be processing more than 15000 such entries and I found that "cut" was using more CPU. So anyone has any idea an alternate command using awk?
Thanks in Advance
Mohammed
