    Unbuntu 14.4安装之后就在终端中使用Tab键不能自动补全，解决办法如下：
    1、利用vi编辑器打开 /etc/bash.bashrc文件（需要root权限）
    sudo vi /etc/bash.bashrc

    接下来会提示输入密码
    2、找到文件中的下列代码
    #enable bash completion in interactive shells#if ! shopt -oq posix; then# if [-f /usr/share/bash-completion/bash_completion ]; then# . /usr/share/bash-completion/bash_completion# elif [ -f /etc/bash_completion]; then# . /etc/bash_completion# fi#fi

    将注释符号#去掉，即改成
    #enable bash completion in interactive shellsif ! shopt -oq posix; then if [-f /usr/share/bash-completion/bash_completion ]; then . /usr/share/bash-completion/bash_completion elif [ -f /etc/bash_completion]; then . /etc/bash_completion fi fi

    3、最后 source一下 /etc/bash.bashrc即可， 即
    sudo source /etc/bash.bashrc
