Dear Adarsh,
In message CAJgxa7d3UPKdNcqegTE1ipOrBpx8jY4Q1MMyuWXQeKvTUbbGrQ@mail.gmail.com you wrote:
=> 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'.
Sorry, I missed that detail.
How do we set an empty value to a hush shell local variable ??
You are right, this is a real bug. Not even using an explicit empty string argument does work here:
U-Boot> foo=hello U-Boot> showvar HUSH_VERSION=0.01 foo=hello U-Boot> foo='' U-Boot> showvar HUSH_VERSION=0.01 foo=hello
Best regards,
Wolfgang Denk
