Question

在终端，我有

    myapp < myfileinput

但是如果我想使用gdb，

它无法正常运行。

如何在这里使用gdb？

Reading symbols from /home/abhishek/maxtest...done.

(gdb) run < input.txt

这对我来说很有用。想知道这是否是你想要的。

Answer 2

尝试在gdb中运行您的应用程序？

(gdb) file /usr/bin/head
Reading symbols from /usr/bin/head...(no debugging symbols found)...done.
(gdb) run -2 < /etc/passwd
Starting program: /usr/bin/head -2 < /etc/passwd
root:x:0:0:root:/root:/bin/bash
daemon:x:1:1:daemon:/usr/sbin:/bin/sh

Program exited normally.
(gdb)

编辑：或者：

gdb -q -ex 'set args -2 < /etc/passwd' /usr/bin/head
Reading symbols from /usr/bin/head...done.

(gdb) run
root:x:0:0:root:/root:/bin/bash
daemon:x:1:1:daemon:/usr/sbin:/bin/sh

Program exited normally.
(gdb) quit
