How to add the contents of a file?

Prateek007 · November 25, 2009, 2:29pm

Hi

I have a file named Data

cat Data

1797548295
2420652689
513068908
1426750759
3229436285
2710691077

i want to sum all these lines, can we use any direct command for that in unix.

Thanks in advance.

awk '{s+=$1} END { print "sum=", s} '  inputfilename

Just to add, to prevent seeing 1.20981e+10, use printf instead of print...

Or use Perl instead. (Sorry, couldn't resist !)

$
$ cat data
1797548295
2420652689
513068908
1426750759
3229436285
2710691077
$
$ perl -lne '$x+=$_; END{print "Sum = ",$x}' data
Sum = 12098148013
$

... after all, no solution would be complete without a Perl one

and a shell version!

while read d;do s=$((s+d));done<data;echo $s

Or:

paste -sd+ data|bc

With Perl:

perl -le'print eval join"+",<>' data

With Z Shell:

print ${(e)\$((${(j:+:)$(<data)}))}
