So I run radare2 from the command line with
r2 - and attempt to display the help with the
? command. I read this line which says:
?[??][expr] Help or evaluate math expression
I am not sure how to read this. I assume the first
Help command. And the rest
[??][expr] is evaluate math expression. However, something like this
?? 0xa does not return anything. So, my question is how to correctly interpret this output from the help.
