Specifies the number of elements that will be displayed by this command. Examples We will demonstrate thexcommand using a basic program that defines a byte array on the stack: intmain() { chartestArray[] ="0123456789ABCDEF"; return0; ...
First command x/x $rip outputs 0x40050f <main+15>: 0x00fc45c7. Is it the instruction at 0x40050f? Is 0x00fc45c7 same as mov DWORD PTR [rbp-0x4],0x0 (assembled instruction at 0x40050f)? Secondly, if it is the instruction, what are those hex numbers from the output of com...

Note: The size of the region to watch for defaults to the pointer size if no-x byte_sizeis specified. This command takes “raw” input, evaluated as an expression returning an unsigned integer pointing to the start of the region, after the option terminator (--). Set a condition on a ...
Now, from what I understand, the command that I issue tells the debugger to: x (first one): examine the memory 32: get 32 of what follows x: enable hexadecimal representation w: show meWordsize data. **Note:**I know that I ask about the esp register, but I don't quite fully unde...

七、x命令 八、command命令 一、多线程调试 多线程调试可能是问得最多的。其实,重要就是下面几个命令: info thread 查看当前进程的线程。 thread切换调试的线程为指定ID的线程。 break file.c:100 thread all 在file.c文件第100行处为所有经过这里的线程设置断点。 set scheduler-locking off|on|step,这个是问...
-command command_file, -x command_file 指示GDB在启动时就执行文件中的命令 -batch 执行命令脚本后退出 初始化文件 在启动时,GDB通常会处理一个名为.gdbinit的初始化文件,GDB会在当前目录和home目录下寻找初始化文件(home目录的优先级高于当前目录)。
