Dear Sridhar Addagada,
In message 1327396047.99588.YahooMailNeo@web120201.mail.ne1.yahoo.com you wrote:
What is the behavior of test command when the variable is not present in the uboot env
It should be the same as in any other bourne compatible shell.
set x
Note that "set" for "setenv" may or may not work, depending on your command selection.
if test $x = 1; then echo "Yes"; else echo "No"; fi
This should provoke an error from the "test" command which misses an argument.
in the above case I get Yes echoed back.
That's a bug then. Patches welcome...
Is there any way to test the presence of a variable in uboot script?
This should be possible like in any other shell...
Best regards,
Wolfgang Denk

Alan Turing thought about criteria to settle the question of whether
machines can think, a question of which we now know that it is about
as relevant as the question of whether submarines can swim.
