Local parameters remain local + even if unset; they appear unset within scope, but the previous + value will still reappear when the scope ends. + + Individual elements of associative array parameters may be unset + by using subscript syntax on name, which should be quoted (or + the entire command prefixed with noglob) to protect the sub- + script from filename generation. + + If the -m flag is specified the arguments are taken as patterns + (should be quoted) and all parameters with matching names are + unset. Note that this cannot be used when unsetting associative + array elements, as the subscript will be treated as part of the + pattern. + + The -v flag specifies that name refers to parameters. This is + the default behaviour. + + unset -f is equivalent to unfunction. |
