I know very little about PERL :(
I have list of millions of rows of data. All data values are separated by a comma
I have to count how many rows contain a specific data value
from that sample list, I have to count how many rows have the value 103 for the second data entry, but only if the value in the first column is 101, so for this list the number of rows with 103 in the second data entry where the first value is 101, would be 1
I have a previous script (attached) from "ozo" which counts the rows with particular values in the first column.
Could you alter this script (as it works very fast) to count the number of rows with 103 in the second column only where the value 101 is in the first column ?
Thankyou very much in advance count1.txt
