Hello,

I am having trouble figuring out how to capture the output from remote commands or better yet how to run commands remotely so I can right some conditions in my capistrano deploy.rb file. For instance, One of the things I would like to do is create a file on the remote system if the file doesn't exist.

What is the appropriate way to do this using capistrano? Am I able to just use the Net::SSH commands out of the box? Is there another set of commands I should be looking? Is there a list of commands somewhere?

What I came across in my searches are:

https://github.com/capistrano/capistrano

https://github.com/capistrano/sshkit

But didn't see any examples of how to capture this to use in my code if its possible.

Some things I have tried are:

execute "ls -al /some/directory"

run "ls -al /some/director

`ssh name@server 'ls -al /some/directory` #this works but I don't feel it is the right way

Sorry if this is such a basic question, I just can't seem to wrap my head around it.
