(i)Wani
(ii)根(很明显！)

我的用户Wani的.bashrc的内容是：

# .bashrc
 echo "Hello"
 # Source global definitions
 if [ -f /etc/bashrc ]; then
    . /etc/bashrc
 fi

 # User specific aliases and functions

现在登录到root后，我键入以下命令：

[root@Dell Wani]#touch try.txt
 [root@Dell Wani]#service sshd start
 [root@Dell Wani]#scp try.txt Wani@localhost:~/
 Wani@localhost's password: 
 Hello
 [root@Dell Wani]#

现在我登录到Wani，然后键入：

[Wani@Dell ~]$ cat try.txt
 cat: try.txt: No such file or directory
 [Wani@Dell ~]$

现在我再次登录到root并使用-v键入相同的命令：

[root@Dell Wani]# scp -v morph.log Wani@localhost:

任何人都可以告诉我们这里发生了什么？为什么文件不能从根目录复制到Wani？
