Using awk to read a field
I am trying to output the total number of records that have name and address within there specific fields i.e. $6 (surname) $9 (address). The file that redirects in is a csv file.

The code is wrong somewhere as i have another awk similar to this that reads in the same file and that works perfectly.

Please see attached code:

OFS=$IFS
IFS=","
#count on address
awk '

BEGIN {
FS=",";
OFS=",";
NA=0;
}

{
if ($6 == /[a-zA-Z]/ && $9 == /[a-zA-Z0-9]/)
{
NA++;
}

}

END {
printf ("%s", NA);
}

' < ../$CUSTOMER_DIRECTORY/"$input_file_name" |\
read NA

IFS=$OFS

Can someone tell me what is wrong with this?Smilie

Thanks Klashxx

It worked, Simple solution, I'd looked at that for a while and got frustrated. I had try'd ~ before i sent this post and it was wrong but i must have changed the syntax layout somehow.

Once again thanks for helping me on thisSmilie
