Question about Hostingrails.com or Linux in general re runni

Hi:

I’m using HostingRails.com to host my rails projects. Their
documentation is pretty good. I recently deployed a second app but now
my first is not working (the second is). They host on linux. My
questions:

  1. How do I know my app is running? I used ps -aux but can’t identify
    processes with any given rails project.

  2. If it had stopped, how would I start the app again. I’ve been
    using Locomotive up till now. Locomotive is great. It includes a nice
    shiny “START” this app button. I have no idea what the command line
    equivalent is.

  3. Does anyone have an example of a .htaccess file that is working at
    hostingrails.com to deploy a second app. I am particularly curious
    about the rewrite rules and would like to see them in the context of
    the whole .htaccess files.

If anyone can help me, those who like me will be truly grateful.
thanks in advance.
