Capistrano 3.x capture output line by line

Question

In Capistrano 2.x you could capture the output line by line using

run "ls -la" do |channel, stream, data|
    puts data
end

This does not work in Capistrano 3.x, and the capture and execute commands do not seem to provide the same functionality.

Is there a way to replicate the 2.x behaviour in 3.x?

Answer 1

output = capture('cat ~/file.cnf')
output.each_line do |line|
    puts line
end

Thats how I read lines using capture. If you want to capture something specific on a line you can use

if line.include? 'user'
