File.open("/tmp/test") do |file|
  file.each_line("e") {|line|
    puts "Got #{ line.dump }"
  }
end

irb で「IOError: クローズド ストリーム」を返します。しかし、それがファイル 'test.rb' に保存されている場合、ruby test.rb- は正常に動作します。Ruby バージョン: ruby​​-2.0.0-p247、ruby-2.1.0-preview1、Ubuntu、Mac OS。私は何を間違っていますか？

user:ads user$ echo "a\nb\nc" > /tmp/test
user:ads user$ irb
2.1.0-preview1 :001 > File.open("/tmp/test") { |file| file.each_line { |line| puts "Got #{ line.dump }" } }
Got "a\\nb\\nc\n"
IOError: closed stream

- ls = File.directory?(f) ? `ls -adlF #{f.path.shellescape}` : `ls -alF #{f.path.shellescape}`
+ ls = `ls -adlF #{f.path.shellescape}`
