Hello Wolfgang Denk,
=> localvar= => showvar HUSH_VERSION=0.01 target=pxe devnum=1 localvar=hello
When 'localvar' is assigned an empty value , the 'showvar' command displays the previously assigned 'hello'.
How do we set an empty value to a hush shell local variable ??
Regards, Adarsh

You cannot. Local variables can be set to an empty value, but they cannot be deleted.
Note that there is no functional difference between a non-existing local variable and one with an empty value anyway. Same as in other shells.
Best regards,
