[Solved] Changing File Permissions Outside Home Directory

[notyourbuddy]

If I have a file in my Home directory I can modify its permissions no problem-o.

But, when I try to modify the permissions of a file located on a separate NTFS partition I can't seem to get 'er working. No errors are being returned so not particularly sure what Linux wants me to do.

Here is my file structure:

/media/Shared/Source_Code/Cross_Platform/a.out

/media/
owner: root
drwxr-xr-x

Next 3 levels have identical permissions

/Shared/Source_Code/Cross_Platform
owner: chris
drwx-----

a.out
owner: chris
-rw-----

Specifically just trying to give myself executable permissions on a.out

Following two commands execute fine, but the file permission doesn't change.

chmod u=rwx a.out
chmod 700 a.out

Re: Changing File Permissions Outside Home Directory

For non-posix filesystems (like ntfs), you can't change file permissions individually (or when they are mounted), as these filesystems don't support posix style permissions.

For ntfs, you can change permissions at mount time by using umask (files and directories), dmask (directories) and fmask (files) mount options. If you have an /etc/fstab line for your ntfs filesystem, you could add the option there, examples:
1. fmask=0077 (all files on the ntfs filesystem will have rwx --- --- permissions once mounted)
2. umask=0000 (all files and directories will have rwx rwx rwx permissions once mounted)
