No, you both are wrong.
See the following:
funct1() {
local ifacelist
funct2
funct3
}
funct2() {
# fill ifacelist
ifacelist="foo bar"
}
funct3() {
# use ifacelist
for var in $ifacelist; do
echo $var
done
}
If you do so ifacelist is valid for all three functions but NOT for the
calling script or a calling function.
And that is what I want.
