Here's what I have now, and this works basically, though still need to
understand the set construct:
set -- one two three
Sets the position parameters $1 $2 and $3 to one two three respectively
set -- "hello world" foo bar
$1="hello world"
$2=foo
$3=bar
somefunc()
{
echo $1
echo $2
echo $3
}
somefunc "hello world" foo bar
HTH
one thing I didnt find yet in any docu: how can I catch if a string is
entered instead of a number with read?
if ! printf "%d" $n >/dev/null 2>&1; then
echo "You didn't enter a number"
exit 1
fi
Also if there's still a better / shorter way to do the same I would love
to hear about!
Many ways to skin a cat. If it works for you then great!
Thanks
