Mac/Linux环境下，给zsh添加zsh-autosuggestions插件：

git clone git@github.com:zsh-users/zsh-autosuggestions.git
# git clone https://github.com/zsh-users/zsh-autosuggestions
mv zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/
python -c "import os,sys;p=os.path.expanduser('~/.zshrc');f=open(p);s=f.read();f.close();v='zsh-autosuggestions';c='You can run the following command to activate plugin:\n\n    source '+p+'\n';v in s and sys.exit(c);ss=s.splitlines();a='plugins=(';t=[i for i in ss if i.startswith(a)];assert t, 'Failed to auto change, you can manually edit {}'.format(p);line=t[0].replace(a,a+v+' ');new=s.replace(t[0],line);f=open(p,'w');f.write(new);f.close();print(c)"
source ~/.zshrc

效果如下：

如果出现的提示就是想要的结果，直接按向右的箭头就能自动补全了
