阅读更多关于 How to give file permission to a specific user in a Group?

问题 I have a Group 'g1' having 2 users Alice and Bob. I want to share a file 'file1' with both of them with different permissions.(for Alice read only and for Bob Read+write) 回答1: Assuming Bob can own the file the following should work for you. $ chown Bob:g1 file1 First set the ownership of the file to Bob to allow for read+write access and set the group ownership to the g1 group. $ chmod 640 file1 Set the owner to a read and write and set the group to read only. This is a common permission

Delphi 2009 classes / components to read/write file permissions

阅读更多关于 Delphi 2009 classes / components to read/write file permissions

Does anyone have a set of classes / components that will work with Delphi 2009 (Unicode) to read and write NTFS file permissions? There was a thing called "NTSet" - but they stopped development at Delphi 2006 about 3 years ago :-( Any other takers?? Thanks! Marc JCL has units to deal with file permissions, and they claim D2009 compatibility. Colin Wilson's "NT low-level" component set wraps the APIs you need, and supports Delphi 2009 as well as earlier releases. However you may need to rely on the MS documentation and samples if you need detailed help to implement a specific operation. You can

阅读更多关于 PHP - Protecting site from folders with 777 permissions

问题 Usually, I try to set my folders to have permission 775, but some web-hosting refuses to let PHP writes or move files to any folders unless it has permission 777 (it may be open_dir or safe mode).

How can I get the default file permissions in Python?

阅读更多关于 How can I get the default file permissions in Python?

I am writing a Python script in which I write output to a temporary file and then move that file to its final destination once it is finished and closed. When the script finishes, I want the output file to have the same permissions as if it had been created normally through open(filename,"w") . As it is, the file will have the restrictive set of permissions used by the tempfile module for temp files. Is there a way for me to figure out what the "default" file permissions for the output file would be if I created it in place, so that I can apply them to the temp file before moving it? For the

Im building a "premium" section of my site and Im in a need to give download access to files in a remote directly (on a different server), to users with special privileges (accounts stored in mysql db). My site is coded in php/mysql so a php solution would be great. direct all download links to a php file that'll do all the credential checking. you can call the file download.php pass along parameters via cookies, get, post, session, or whichever manner you verify privileges. once credentials are verified, you can send an appropriate header. if it's an image, the header would be header("Content
