Various field separators:
Code:
awk '$2=NR' FS=\",\" OFS=\",\" file

Code:
awk '$4=NR' FS=\" OFS=\" file



--
JFF:
Code:
sed = file | sed 'N; s/\(.*\)\n\([^,]*,"\)/\2\1/'

Add comment string to a column in a file
Great! This did the trick:
Code:
awk '$2="\"" NR "\""' FS=, OFS=, infile

Now I need to add a comment string to a couple of fields for every line in the file. Different comment string for each field.

In below file, fields 7 and 8

Code:
"R","1","t0000684","","10/31/2013","10/31/2013","","","","750.23"

Thank you again.

try something like:
Code:
cmt1="this is comment 1"
cmt2="this is comment 2"
 
awk -v cmt1="$cmt1" -v cmt2="$cmt2" '
{$2="\"" NR "\"";
 $7="\"" cmt1 "\"";
 $8="\"" cmt2 "\""; } 1
' FS=, OFS=, infile
