ruby 1.9 简单的文件操作

#读文件f = File.open("myfile.txt", "r")f.each_line do|line|puts "I read this line: #{line}"end

File.foreach("myfile.txt") do|line|puts "I read this line: #{line}"end

f = File.open("myfile.txt", "r")line = f.getsputs "The line I read is: #{line}"

#写操作File.open('filename','w') do |f|  f.puts linesend

#得到当前目录所有文件名    files = Dir.glob('*.rd')

#删除特定目录所有文件名Dir.glob('*.rd').each{|f| File.delete f}
