vim自定义配置

vim-plug installation

curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

if the command above can not work, you can just copy plug.vim into .vim/autoload

cd ~
git clone https://github.com/junegunn/vim-plug
mkdir .vim/autoload
cp vim-plug/plug.vim ~/.vim/autoload

 vim usage

查看vim版本

1. 在shell下键入 vim --version

2. 在打开的vim编辑器内键入 :version

支持系统剪贴板

1. vim --version | grep clipboard   来查看xtem_clipboard前面是+还是-，如果是+，说明可用，如果是-，则不可用

2. 如果不可用，sudo apt-get install vim vim-scripts vim-gtk vim-gnome 来安装，安装完成后再次查看，应该能看到xterm_clipboard前是+

3. 在vim中使用shift+v来选择文本，"+y 来复制， 这样就复制到系统剪贴板上了，然后再在text或者网页端使用ctrl+v来粘贴了

 同时打开多个文本文件, 而这些文本文件分别在不同的tab里, 可以使用tabn或tabp来switch

vim -p <file1> <file2> <file3> ...
