Adding indexes with PERL

Hello. I'm trying to self learn Perl and am stuck. I have a data.csv file that contains the following:



Code:
5,10,15,20,15,30
1,2,3,4,5
3,10
11

I'm trying to get Perl to take the indexes and add them all together to get 134. It says I need to use split and invoke the file via
<> (built-in provides data from files and standard-in) the command line. So I'm doing ./test.pl data.csv to run it but I'm just
getting 4 lines containing a single 0. Any pointers?

Here is the code I have so far:
Code:
#!/usr/bin/perl

while (<>){
$total=(split/,/,$input);

print$total;
print ("\n");
}

Eric7giants,

Please do not add color to your code. It makes reading almost impossible.

Please edit your post and remove all the color you added.

Thanks.

Your task is pretty basic. You will find a lot of examples if you...

... search google for "perl read from stdin" ...
... read the documentation for the functions, e. g. perldoc -f split

I do not see where you are assigning a value to your variable $input, which you'd like to split.
