有没有这样一个需求：
同时向几十上百台Linux服务器上传文件并执行命令，如果一个个来，那你就真是挨踢民工。程序员要发挥自己懒惰的个性，借用Net::SSH和net::SCP用Ruby写个脚本你会发现非常简单。

Net::SSH和Net::SCP是两个Ruby操作SSH的gem包。Net::SSH相当于cmd，专门用于执行命令；Net::SCP专门用于传输文件。它们俩结合，可以做任何SSH client能做的事情。


安装：
gem install net-ssh
gem install net-scp
以下所有代码都引用这段代码

function insert_medias(s){
  //var app_path="/kpy/dc";
  var app_path="";
  if(s==1){
    jsonurl=app_path+"/tempmedias/show";
    see_prefix=app_path+"/new_see/";
    $.getJSON(jsonurl, function(data) {
    var items = [];
    $.each(data, function(index, media) { 
      mediasrc=see_prefix+media.grid_id;

我们本地的git目录下, 其实分为三种类型的文件: working tree、index file和native repository;
working tree就是我们当前修改的文件;
在使用"git add"命令后, git就会把diff合入index file(通过“git diff”来查看working tree与index file的差别);
再使用"git commit"命令, 把修改合入native repository("git commit -a"相当于"git add" + "git commit"; 在commit之前, 可以通过""git diff --cached"来查看index file与commit的差别);

其实, 还可以使用"git reset"命令来还原git节点.
"git reset --hard patch-hash-name" 可以使working tree、index file以及native repository彻底回复到指定的节点;
"git reset --mixed patch-hash-name" 可以使index  file和native repository被还原;
"git reset --soft patch-hash-name" 可以使native repository被还原;

Place your new font in the folder app/assets/fonts.

Tell the server where the fonts are located and that it has to precompile assets with those specific file extensions. You probably only have to add the following lines to your config/environments/production.rb file since you are not precompiling your assets locally. If you are, then also add these lines to your config/environments/development.rb file:

# Add the fonts path
config.assets.paths << Rails.root.join('app', 'assets', 'fonts')

# Precompile additional assets
config.assets.precompile += %w( .svg .eot .woff .ttf )
  Declare your font in your css like so:
