Diciamo che ho la seguente stringa:
something1: +12.0 (some unnecessary trailing data (this must go))
something2: +15.5 (some more unnecessary trailing data)
something4: +9.0 (some other unnecessary data)
something1: +13.5 (blah blah blah)
Come lo trasformo in semplicemente
+12.0,+15.5,+9.0,+13.5
in bash?
