我如何通过ssh直接登录到rails控制台？

Question

我时不时重复以下命令：

ssh username@servername 
cd /projects/rails_project 
bundle exec rails c production 

我想创建一个shell脚本，使别名此文件的运行生产控制台一行。如果我用这3条命令写了简单的脚本，那么它就不起作用了。

我该怎么做？

只需把它作为一个参数：

ssh username@servername 'cd /projects/rails_project && bundle exec rails c production' 

从man ssh：

SYNOPSIS 
     ssh [options] [user@]hostname [command] 
     ... 

     If command is specified, it is executed on the remote host instead of a 
     login shell. 
     ... 

     When the user's identity has been accepted by the server, the server 
     either executes the given command in a non-interactive session or, if no 
     command has been specified, logs into the machine and gives the user a 
     normal shell as an interactive session. All communication with the remote 
     command or shell will be automatically encrypted.
