function foo() {
A=$@...
echo $A
}

foo bla \"hello ppl\"

I would like the output to be:
\"bla\" \"hello ppl\"

What do I need to do in

Answer 1

You can use "$@" to treat each parameter as, well, a separate parameter, and then loop over each parameter:

function foo() {
for i in "$@"
do
    echo -n \"$i\"" "
done
echo
}

foo bla "hello ppl"
