linux - 使用 gdb 调试 wget 命令

Question

我要调试wget带有一个特殊的 url。

那么如何将url传给gdb呢？我已经尝试过 --args <the url> , 但它不起作用。

请帮帮我。

附言: 我用了gdb以错误的方式gdb wget --args http://www.google.com/ ，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.
