When doing live debugging, it’s not uncommon to have to repeat a set of commands until a condition becomes true or false.
There are several ways to do this, and one of them is through the z command.
You can create automated commands using this instruction: just think about the possibilities!
Here is an example:
.echo REGISTERS; tr; .echo CALL STACK; kL 1000; z(@eip != 66FCA607 )
The line above displays the registers and the call stack while running the application. At some point, when the next instruction address is 66FCA607, it stops the execution.
