Question

Is there a way in a Ruby script to sftp to a server and run some commands.

Here is my script

Net::SFTP.start(IP_ADDRESS, 'root', :keys => ["/Users/user/.ssh/id_rsa"]) do |sftp|
    sftp.mkdir! "/srv/new_dir"
    sftp.dir.foreach("/srv/crm/current") do |entry|
      puts entry.longname
      sftp.file.open("/srv/new_dir", "w") do |f|
        f.puts entry
      end
    end
end

Basically I am trying to sftp to the server and copy a folder into a new folder and I would like to restart apache. I tried this:

FileUtils::sudo "/etc/init.d/apache2 reload"

but that doesn’t work. Any ideas what I am doing wrong, or whether this is even possible?

Since you aren’t really doing any file transfers, I don’t think you need to be using SFTP. You could simply rewrite this script using Net::SSH. Then you have normal access to a shell and your Apache command is simply another step in this process.
