def xpopen command, *mode, &block
env, commands = expand_command(command)
command = [env_quote(env), command].join(' ')
Logging::open do
case mode[0]
when nil, Hash, /^r/
puts "#{command} |"
else
puts "| #{command}"
end
IO.popen(env, commands, *mode, &block)
end
end
Executes command similarly to xsystem, but yields opened pipe.
