I know this question was asked a while ago, but I will try to answer it anyway for future users:
About mask in file system:
The use of masks in linux filesystem is to control
- read, write, and execute permission among different users/groups for specific files and folders. I emphasize the word 'control' because masks are not same as giving permission. Just the opposite; they are to control or limit permission. So, if you want to set 777 for a file as permission, then you have to use 000 as mask for that file. For permission 655, mask will be 122 (i.e: for permission xyz mask will be (777-xyz)).
What is umask,dmask, and fmask?
- umask = user mask (folder and directory!)
- dmask = directory only mask
- fmask = file only mask
How To Set Executable Permission for NTFS Partition files?
Run this command to get UUID (Universally Unique IDentifier) for every NTFS drive:
$ sudo blkid
You will get output like this:
/dev/sda6: LABEL="Software" UUID="FEDC5DB5DC5D6943" TYPE="ntfs"
/dev/sda7: LABEL="Works" UUID="585AD06A35149024" TYPE="ntfs"
Now edit the fstab file:
$ sudo vim /etc/fstab
In the fstab file add/edit every drive specifying line with the following options (remember to use other option carefully, as adding any other option may cause problem):
So after edit/adding nfts drives your portion of fstab file will look something like this:
#<file system> <mount point> <type> <options> <dump> <pass>
UUID=FEDC5DB5DC5D6943 /media/software ntfs defaults,auto,umask=002 0 0
UUID=585AD06A35149024 /media/works ntfs defaults,auto,umask=002 0 0
Above umask will set permission equal 775, i.e read-write-execute for admin user (that is you) and admin user group and read-write permission for other users.
For samba share you might need to use
gid=YourGroupID,uid=YourUserID in the option set. You can find YourGroupID and YourUserID values using the following command:
$ id YourUserName
Now Unmount your drives if already mounted:
$ sudo umount -a
Then mount by this command:
$ sudo mount -a
After mount you can use the drives in whatever way you want.
