Switch to root user under Linux, how to switch your own vim

· The easiest way is to copy /home/myname/.vimrc to /root/.vimrc
· You can use the soft link of ln to point /root/.vimrc to /home/myname/.vimrc

ln -s /home/myname/.vim   /root/.vim
ln -s /home/myname/.vimrc /root/.vimrc

If you use someone else's configuration, such as spf13-vim, then we need to re-connect the vim soft link under /home/myname/ and point it to the root directory

ln -s /home/myname/.vim   /root/.vim
ln -s /home/myname/.spf13-vim-3/.vimrc   /root/.vimrc
ln -s /home/myname/.spf13-vim-3/.vimrc.before  /root/.vimrc.before
ln -s /home/myname/.spf13-vim-3/.vimrc.bundles /root/.vimrc.bundles
