Question

我想使用特殊网址调试wget。

那么如何将url传递给gdb？我已经尝试了--args <the url>，但它不起作用。

请帮帮我。

PS：我以错误的方式gdb使用了gdb wget --args http://www.google.com/，它应该是gdb --args wget http://www.google.com/

这应该有效：

[ ~]$ gdb -q --args /usr/bin/wget https://www.google.com/
Reading symbols from /usr/bin/wget...Reading symbols from /usr/lib/debug/usr/bin/wget.debug...done.
done.
(gdb) start 
Temporary breakpoint 1 at 0xbda0: file main.c, line 1186.

1189      int nurl;
1190      int retconf;
(gdb)
