I am trying to to view the groups that belong to a directory and to enable www-data to be an admin of a directory so I am able to delete files that are within it using php unlink functionality. I have looked on the net and tried a number of things which chgrp and chmod etc but I am not getting anywhere. Could someone point me in the right direction. I believe I am just doing things in the wrong order and need some guidance. I know a little bit of linux but not a great deal and I think this is my trouble.

Context: The folder is within a NAS drive. Apache is setup to point to the NAS drive and content is served as expected. However, when it comes to deleting files from a sub folder I recieve the unlink permission denied error within php (assuming this is due to www-data not having access to delete from the folder)

You are very close, the chown command sets user and group ownership. In order to change the user or group owner for a directory or file see the exampled below.

ex. chown user:group /path/to/directory/or/file

If you would like to change the ownership of a directory and all the files and sub-directories you can use a command like below, but be very, very careful, it can be a dangerous command if not used prudently.

chown user:group /path/to/directory -R

  • HI, I navigated to the folder that contains the folder I wanted to set the permissions on and I done chown www-data:www-data dirName -R. However, it still does not work. Do I have to use the full path to it. Does it make a difference that the folder is located on a NAS drive that is mapped to the box?
