change owner problem

Asked by bleuzolex

I tried to change the owner of an avi file by using the following command " sudo chown <newowner>:<newgroup> <filename>" but nothing changed. The command didn't match the error message but the previous owner (root) still remained.
Thks in advance

Please tell... exactly what error message your are getting.

Also files on non-linux partitions such as FAT or NTFS do not have the same file attributes such as ownership/permission and cannot be modified with chown/chmod. Since these attributes do not exist, they are set for all files when the volume is mounted.

Ownership and permission for NTFS files are set when the drive is mounted. Ownership should not really be a problem because typicall NTFS drive are mounted as read/write for everyone by default. If you wish to change the ownership of group permission of your mounted drive you will have to edit your /etc/fstab file

Please read the section regarding mounting NTFS partition with fstab
https://help.ubuntu.com/community/Fstab

To find out more about mounting options please, from the terminal please type
man ntfs-3g
man mount

Here are some common mount options. Typically owner and group is set on with the following mount options uid and gid. For example setting uid=1000 will set ownership of all files to user 1000 which is the primary user of the machine. Using gid=100 will set permission to the group user. Using umask=000 will set 777 permission.

Hope this helps
