i have file which contains data like this every day.i need to pull up a report for counting the 203's in that file for each subscriber id.there are around 200 subscriber id's. all ths Y's which i have written in the script are the subscriber id's.could some one give me an idea as to how do it in a better way.

Script:

#!/bin/sh
set -x
thisday =`date +%y%m%d00010202.TLG`

for Y in 2 144 9 129 16 37 42 45 87 104 53 40 62 63 51 158 18 19 20 21 50 67 82 116 64 100 141 168 170 171 49 84 85 35 34 70 61 69 8 26 27 28 78 79 32 33 10 11 130 25

do
echo "$Y 203's = ";`cat $thisday | grep ^203 | grep "2C,$Y, | wc -l`; done

That's complicated , this should work:

awk -F, 'NR==FNR{_[$0];next}$1==X && $3 in _{a++}END{print a}' X="203" subscriber.list `date +%y%m%d`00010202.TLG

should i put this into a subscriber list file

You should put each subscriber id on a separate line

2
144
9
etc.

ins@ARTMGA01> awk -F, 'NR==FNR{_[$0];next}$1==X && $3 in _{a++}END{print a}' X="203" a.out `date +%y%m%d`00010202.TLG

i get this when i run the above query i am not getting the count of 203's for each subscriber id

subscriber id is the list above

$ nawk -F, 'NR==FNR{_[$0]=0;next}$1==x && _[$3]!=""{a[$3]++}END{for(i in a){print i,a[i]}}' x=203 subscriber.list `date +%y%m%d`00010202.TLG
