如何使用inputredirect的gdb？
在terminal，我有
myapp < myfileinput 但是如果我想用gdb，
gdb myapp < myfileinput
它没有正确运行。
如何在这里使用gdb？
~$ gdb <executable> GNU gdb (Ubuntu/Linaro 7.3-0ubuntu2) 7.3-2011.08 Copyright (C) 2011 Free Software Foundation, Inc.

Reading symbols from /home/abhishek/maxtest...done. (gdb) run < input.txt
这是为我做的伎俩。 想知道这是你在找什么。
尝试从gdb内运行你的应用程序？
(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
你可以试试这个
（gdb）运行<input.txt
