Summing results resident in a var

[sumncguy]

fl1psiz=`$sn $ip 1.3.6.1.4.1.9.9.10.1.1.4.1.1.4 | sed 's/.*GER: //' | tr '\012' ' '`

The line above returns the line shown below. I want to add these values together.

8388608 8388608

Whats the best way to do this ?

fl1psiz=`$sn $ip 1.3.6.1.4.1.9.9.10.1.1.4.1.1.4 | sed 's/.*GER: //' | tr '\012' ' '` | while read one two
do
  expr $one + $two 
done

I think Columb meant:

fl1psiz=`$sn $ip 1.3.6.1.4.1.9.9.10.1.1.4.1.1.4 | sed 's/.*GER: //' | tr '\012' ' '`
echo $fl1psiz | while read one two
do
  expr $one + $two
done

Or perhaps this ?
fl1psiz=`$sn $ip 1.3.6.1.4.1.9.9.10.1.1.4.1.1.4 | awk '{sub(/.*GER: /,"");t+=$0}END{print t}'`

Hope This Helps, PH.

Thanks works great.

One other thing that I forgot to ask was ...

How do I change (round) 16777216 to the nearest Megabit ?
ie 16M or even 17M which is plain enough.

Also, is there a decent online resource for ksh and mathmatics ? I have the Oreilly Ksh Scripting and it doesnt go into this kind of thing ... could have missed it I suppose.

Thanks again.

perhaps, the home of Mr. Korn himself. And of course the ksh man page. For most things you can put a simple mathematical expression between $(( and )), e.g.

[tt]$ echo $(( 16777216 / 1024 / 1024 ))
16
$[/tt]

You can just divide by 1024 twice to get to Megabits.
