You probably want the capture helper which will run a command on the first
server of a role and return the commands output.
task :check_svn do
status = capture(' svn command that returns status')
# now you can do something with the status.
logger.info status
end
If you just want host names
find_servers(:roles => :app).first.host
Or
find_servers(:roles => :app).map(&:host)
