问题 We have a 150 Gb data folder. Within that, file content is any format (doc, jpg, png, txt, etc).

For that, first I used ArrayList<File> to store all files, then used FileUtils.contentEquals(file1, file2) method. When I try it for a small amount of files(Folder) it's working but for this 150Gb data folder, it's not showing any result. I think first

问题 How do I use Ruby's fileutils to make an alias on Mac's filesystem? Symbolic link would work too, either one. Or would I need to use some sort of shell script to do so? 回答1: Use FileUtils::symlink: FileUtils.symlink(src, dest) To learn how to make an alias via AppleScript, see https://apple.stackexchange.com/questions/51709/can-i-create-a-desktop-shortcut-alias-to-a-folder-from-the-terminal As a side note: except for the aliases (via AppleScript), Ruby will handle this correctly on any

问题 I'm working with ruby 2.0 on windows 7 (unfortunately I have to) and have issue with this code: FileUtils.touch(file) This code is needed to update file.ctime (which probably will have problems too) So, when files is processed I 'touch' them and not processing them in next iteration. How can I deal with it error? ruby_path/fileutils.rb:1137:in 'utime': Permission denied 'path_to_file' Errno::EACCES 'block in touch' 'each' 'touch' example: file = File.new('file_path') FileUtils.mkdir_p(path)

问题 This question already has answers here : Saving path in String (4 answers) Closed 3 years ago . I'm sure this has been answered, but ten different strategies hasn't worked on this issue. If I use C:\Users\Anny\Dropbox\SocialMediaOcto\instructions\Trees\instructions.txt as my absolute path for the file, IDEA cannot read or execute from this path. If I take that same path and paste it into windows explorer, it will execute right away. I dont want to focus on a working directory as this file
