调用gdb自动将参数传递给正在调试的程序 [英] Invoke gdb to automatically pass arguments to the program being debugged

问题描述

我想编写一个脚本（在某些情况下）将执行gdb并自动运行一些带有一些参数Y的程序X.一旦程序执行完毕，用户应该保持在gdb的提示符下，直到s / he显式地退出它。

I'd like to write a script that (under certain conditions) will execute gdb and automatically run some program X with some set of arguments Y. Once the program has finished executing the user should remain at gdb's prompt until s/he explicitly exits it.

执行此操作的一种方法是让脚本将run命令加参数Y输出到某个文件F，然后让脚本像这样调用gdb ：

One way to do this would be to have the script output the run command plus arguments Y to some file F and then have the script invoke gdb like this:

gdb X < F

但是有没有办法在不引入临时文件的情况下执行此操作？

But is there a way to do this without introducing a temporary file?

谢谢。

Thanks.

推荐答案

如果你想通过GDB运行一些命令然后让它退出或者运行完成，只需要执行

If you want to run some commands through GDB and then have it exit or run to completion, just do

echo commands | gdb X

如果您想在运行这些命令后将它留在命令提示符处，可以执行

If you want to leave it at the command prompt after running those commands, you can do

(echo commands; cat) | gdb X

这导致将命令回显给GDB，然后键入 cat 进程，它将stdin复制到标准输出，它被传送到GDB中。

This results in echoing the commands to GDB, and then you type into the cat process, which copies its stdin to stdout, which is piped into GDB.
