如何在ruby的最后修改时间之前订购文件? [英] How to order files by last modified time in ruby?

问题描述

如何在ruby中以最后修改的时间顺序获取文件?我能够将键盘砸得足够大以达到此目的:

How to get files in last modified time order in ruby? I was able to smash my keyboard enough to achieve this:

file_info = Hash[*Dir.glob("*").collect {|file| [file, File.ctime(file)]}.flatten]
sorted_file_info = file_info.sort_by { |k,v| v}
sorted_files = sorted_file_info.collect { |file, created_at| file }

但是我想知道是否还有更复杂的方法?

But I wonder if there is more sophisticated way to do this?

推荐答案

简单地说:

# If you want 'modified time', oldest first
files_sorted_by_time = Dir['*'].sort_by{ |f| File.mtime(f) }

# If you want 'directory change time' (creation time for Windows)
files_sorted_by_time = Dir['*'].sort_by{ |f| File.ctime(f) }
