With the :| + operator, all entries in $name that are also in $array will be removed + from the substitution. Conversely for the :* operation only the + entries that are in both arrays will be substituted. + - Numeric expansions can have a positive or negative step e.g. "{3..9..2}". Negative start and end of ranges are also now supported. |
