I am currently writing a quick script in Ruby that goes through all the contents of two folders, and returns a list of all the files that are not in either of the two folders. Currently what I am doing is storing the paths of all the files of each directory in an array: Find.find(dir1) do |path| if File.file?(path) directory1_file...

Hello, I've got a bug with UTF-8 normalizations: as far as I understood, there's (at least) two ways to write an 'é' in UTF-8 : CC 81 and C3 A9. [After a migration from Mac/OSX to a PC/Linux] I now have a conflict between the paths I store in my database and the actual file system structure, which prevents me from accessing correctly...
Linux has a feature called namespaces, which let you give a different "view" of the filesystem to different processes. In Windows terms, this would be useful for example if you had a legacy program "floyd" that always loaded its configuration from C:\floyd\floyd.ini. If Windows had namespaces, you could write a wrapper script which wou...

Hi, We are setting up two server systems. One of which will host a 3rd party application which will by default save certain data on a local folder: /opt/application/common/recordings How do I create a "writable share" on the other server (with appropriate permissions), so that all these files from the first server are saved on the...

I have a site which is akin to SVN, but without the version control.. Users can upload and download to Projects, where each Project has a directory (with subdirs and files) on the server. What i'd like to do is attach further information to files, like who uploaded it, how many times its been downloaded, and so on. Is there a way to do t...
Basically I write an application which copies/moves files from the local file system to a remote file system over some FTP-like protocol. Would it be a good approach to encapsulate the protocol-specific bits inside of the file system service provider interface? As far as I understand that would make my library work with other applicati...

I'm very new to the world of C++ error handling, but I was told here: http://stackoverflow.com/questions/3622030/checking-for-file-existence-in-c ...that the best way to checks for file existence was with a try-catch block.

Hi, When I copy files from my Linux machine to my external HDD (FAT format), 'git status' shows that files are modified. I guess that occurs because of the file system difference.
