Awk: sum on a column range

[metaltree]

Hello,

I need to sum the values of several columns but want to avoid the $1+$2+$3...+$100 syntax.
I tried the command below, but apparently I'm doing something wrong.

$ cat infile
1       2       3
4       5       6

wanted result

6
15

$ awk -F "\t" '{x=0; for (i=1; i<=NF; i++); x = x + $i; print x }' infile
0
0

 

[PHV]

awk '{x=0;for(i=1;i<=NF;i++)x=x+$i;print x}' infile

Hope This Helps, PH.
