Accessing Processes

Command#run, FiberFunction#run and ProcessFunction#run return a Run::AsProcess instance. And CommandGroup#run returns a Run::ProcessGroup instance. These instances are used for accessing running processes.

For example, if you want to test if a command is successfully terminated, use #success? method.

process = Run::Command.new("try-something-command").run
if process.success?
  puts ":)"
else
  puts ":("
end
