Regarding AWK

Hi,

Since my file that has got input values in the format "1,Mani,23" and I dont know how many such inputs are going to be there.I wrote the following script to print How many however values were there in the file:

while read line
do
count=1
more values | awk '{print $count}'
count=`expr $count + 1`
done < values

It gives me an error as following:
awk: Field $() is not correct.

How can print all the values in the file field by field ie...

if inputs are like this
1,Mani,23
2,San,24,
3,Tom,25
..
..
and so on. How can I print the first field,2nd field and the third field seperately using awk in a loop

Thanx in advance

Mandatory arguments to long options are mandatory for short options too. -b, --bytes=LIST select only these bytes -c, --characters=LIST select only these characters -d, --delimiter=DELIM use DELIM instead of TAB for field delimiter -f, --fields=LIST select only these fields; also print any line that contains no delimiter character, unless the -s option is specified -n (ignored) --complement complement the set of selected bytes, characters or fields -s, --only-delimited do not print lines not containing delimiters --output-delimiter=STRING use STRING as the output delimiter the default is to use the input delimiter -z, --zero-terminated line delimiter is NUL, not newline --help display this help and exit --version output version information and exit Use one, and only one of -b, -c or -f. Each LIST is made up of one range, or many ranges separated by commas. Selected input is written in the same order that it is read, and is written exactly once. Each range is one of: N N'th byte, character or field, counted from 1 N- from N'th byte, character or field, to end of line N-M from N'th to M'th (included) byte, character or field -M from first to M'th (included) byte, character or field AUTHOR
