gdb에서 애플리케이션을 실행 해보십시오.

(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) 

편집 : 또는 :

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

(gdb) run
