关于ubuntu vim编辑问题处理:

由于Ubuntu预安装的是tiny版本，就会导致我们在使用上的产生不便。所以我们要安装vim的full版本。

首先，先卸掉旧版的vi，

root@mgw-virtual-machine:~# apt-get remove vim-common  #卸载

root@mgw-virtual-machine:~# apt-get install vim   #安装full版的vim

root@mgw-virtual-machine:~# vim /etc/vim/vimrc.tiny

注释:

vimrc.tiny   拥有者是root用户，所以要在root的权限下对这个文件进行修改。很简单，这个文件里面的倒数第二句话是“set compatible”，将“compatible”改成“nocompatible”非兼容模式就可以解决方向键变ABCD的问题了。

接下来要解决Backspace键的问题也很简单，在刚才那句话后面再加一句： set backspace=2
