Summing lines in a file

Can anyone tell me how sum values in each record of a file and append that value to the end? For instance a typical record will be:

Code:
FY12,Budget,771100,,,,,,,,,250,-250

I'd like the record to become
Code:
FY12,Budget,771100,,,,,,,,,250,-250,0

which can be put into another file.
Thank you.

Code:

Thank you both very much for the quick response!

Both code sets worked great but what I neglected to mention is that the file has many records and I need to sum record by record and not carry the total.

try this


Code:
awk -F, '{for(i=4;i<=NF;i++){s+=$i}{$(NF+1)=s;s=0}}1' OFS="," file

awk -F "," ' { for( Cnt=NF-1; Cnt<=NF ; Cnt++) { Val+=$Cnt ; }
print $0","Val ;
