All the scripts in my ~/bin have '#!/bin/sh' as the first line, yet the scripts won't run without sh. This problem appeared after I shifted all my personal data to an ntfs partition and made symlinks to them in the home directory. I think I have set the permissions correctly in all the affected folders(774 to directories and files in bin and 664 to all the other files), and added this entry to /etc/fstab:

UUID=5BE8B8E020325D09                                 /mnt/DATA       ntfs-3g auto,users,permissions                       0           0

That's how the problem looks:

saga@terminal:~$ syncit a b
bash: /home/saga/bin/syncit: Permission denied
saga@terminal:~$ sh ~/bin/syncit a b
    <works correctly>

Any idea what's happening here?

I moved my data to sda10

  • 664 files wont auto execute. – Archemar Sep 21 '16 at 13:58
  • As I said, files in bin have 774 permission. – saga Sep 21 '16 at 14:10
  • Can we see ls -l on those files? And also mount command could be useful to see mount options. – Kalavan Sep 21 '16 at 14:15

/mnt/DATA is mounted with the noexec flag. As a quick fix remount /mnt/DATA without noexec, i.e.

mount -o remount,exec /mnt/DATA

For persistence, modify the according entry in /etc/fstab such that this flag is not set by default.

  • So what do I do about it. – saga Sep 21 '16 at 15:07
  • You'll have to remove the noexec flag from the /dev/sda10 line in /etc/fstab. – Johan Myréen Sep 21 '16 at 15:10
  • noexec flag isn't set in fstab. sda10 has auto,users and permissions options set. – saga Sep 21 '16 at 15:14
  • Try adding the exec flag. – Johan Myréen Sep 21 '16 at 15:18
  • I see the mount is a fuse (File system in user space) mount. What does /etc/fuse.conf contain? – Johan Myréen Sep 21 '16 at 15:24
