@@ -87,6 +87,12 @@ Expansion (parameters, globbing, etc.) and redirection as a string, never a pattern, e.g. ${array[(ie)*]} looks for the index of the array element containing the literal string "*". +- The operators :| and :* in parameter substitution allow for array + subtraction and intersection in the form ${name:|array}. 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. |
