Ruby如何计算文件夹大小

计算文件凯亏枝大小的盯敏不会，给你看看行数计空没算吧

Ruby文件行数计算代码示例：

module Enumerable

# function to get total lines for file

def total_lines

lines = 0

each_with_index {|content,lines|}

return lines+1

end

end

class CheckLines

require 'find'

@check_type = %w{txt rb erb yml html css xml}

def initialize(directory)

@total_lines = 0

if File.directory?(directory)

@directorydirectory = directory

@contents = {}

self.go

else puts "#{directory} is not a directory! check it out!" and return

end

end

def go

if @directory

Find.find @directory do |path|

pathpathlite = path.gsub(@directory,'')

if File.file? path

File.open path do |f|

tmp_line = f.total_lines

@contents.store(pathlite,tmp_line)

@total_lines += tmp_line

end

end

end

puts @total_lines

end

end

def details

@contents.each do |key,value|

puts "#{key} file has lines of #{value}"

end

end

end

file = File.new(“testfile”, “r”)# … process the filefile.closetestfile是想要 *** 作的文件名，”r”说明了文件的 *** 作模式为读龋可以使用”w”表亩此缺示写入，”rw”表示读写。最后要记得关闭打开的文件，确迅辩扒扮保所有被缓冲的数据被写入文件，所有相关的资源...
