I’m working on an MIT-licensed library that helps Python programs monitor file system events as portably as possible. There are differences that I’m trying to iron out. Highly alpha version at the moment: Check it out here: http://github.com/gorakhargosh/watchdog/ Patches and contributions are welcome.
I agree that hard-linking folders/directories can cause problems if not careful, but they have a very definite advantage – Time Machine is a perfect example. Without them it simply would not be practical as the duplication of redundant versions of files would very quickly consume even the largest of disks. Snow Leopard can create hard … Read more
There are almost no restrictions – apart from “https://stackoverflow.com/” and ‘\0′, you’re allowed to use anything. However, some people think it’s not a good idea to allow this much flexibility.
EDIT: As noted in the comments, the code below is valid for versions of boost::filesystem prior to v3. For v3, refer to the suggestions in the comments. boost::filesystem does not have wildcard search, you have to filter files yourself. This is a code sample extracting the content of a directory with a boost::filesystem‘s directory_iterator and … Read more
As suggested elsewhere, this is not usually what you want to do. It is usually best to create a temporary file using a secure method such as File.createTempFile(). You should not do this with a whitelist and only keep ‘good’ characters. If the file is made up of only Chinese characters then you will strip … Read more
The terminology used is a bit different from what you’d find in the Unix world, however in terms of having an integer that uniquely identifies a file, NTFS and some Windows API expose the concept of “file IDs” which is similar. You can query the file ID of an open handle via GetFileInformationByHandle. See nFileIndexHigh, … Read more
I have tried this with and without the WRITE_INTERNAL_STORAGE permission. There is no WRITE_INTERNAL_STORAGE permission in Android. How do I create this file for writing? You don’t, except perhaps on a rooted device, if your app is running with superuser privileges. You are trying to write to the root of internal storage, which apps do … Read more
mktemp randomizes the name. It is very important from the security point of view. Just imagine that you do something like: echo something > /tmp/temporary-file in your root-running script. And someone (who has read your script) does ln -s /etc/passwd /tmp/temporary-file before. This results in /etc/passwd being overwritten, and potentially it can mean different unpleasant … Read more
Tested in laravel 5.5 $extension = $request->file(‘file’)->extension();
xcopy “C:\SomeFolderName” “D:\SomeFolderName” /h /i /c /k /e /r /y Use the above command. It will definitely work. In this command data will be copied from c:\ to D:, even folders and system files as well. Here’s what the flags do: /h copies hidden and system files also /i if destination does not exist and … Read more
