@ -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.
