Appending to a variable

Jan 1st, 2009

Hi,
how do you append to a variable? I can only get it to work with a seperate file like this:

printf $number1 >> sum.txt

I tried this :

$number1 >> $sum

but it says $sum: ambiguous redirect, any ideas?

Hey there,

For scripting in shell, you can just concatenate the two variables

•

sum="hi "
host # number1="there"
host # echo $sum
hi
host # sum="${sum}$number1"
host # echo $sum
hi there

Hope that helps

, Mike
