用gdb调试wget命令

Question

I want to debug wget with a special url.

So how to pass the url to gdb? I already tried with --args <the url> , but it dosen't work.

Please help me.

ps: I used gdb in the wrong way gdb wget --args http://www.google.com/ , it should be gdb --args wget http://www.google.com/

Answer 1

This should work:

[ ~]$ 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.
