/etc/fstab

[MikeCyber]

Hi
in 10.04 I mount a ntfs partition and can execute a *.sh there. But on 12.04 I cannot execute that shellscript. I don't understand the fstab. What do I need to change to get back 10.04 functionality?
Thanks

Please provide more info.

Do you want to mount ntfs partition permanently?

The /etc/fstab file contains static filesystem information. It defines how storage devices and partitions are to be mounted and integrated into the overall system. It is read by the mount command to determine which options to use when mounting a specific device or partition.

You need execute permission to run a file, and for the Windows file systems FAT and NTFS the file permissions are set when the partitions are mounted (they cannot be set individually).

One solution is to collect your own executable binary files (compiled programs) and shell-scipt files in your own bin directory

mkdir ~/bin
cd ~/bin
mv 'files-to-execute' .

and set the executable bits

chmod ugo+x 'files-to-execute'

Another method is to give all files in the FAT or NTFS partition execute permission (in /etc/fstab)

A third method works for shell scripts: run them as a parameter to sh, bash, csh etc:

bash 'file-to-execute' parameter1 parameter2 ...

sh script.sh

Is there an entry in /etc/fstab for your NTFS partition?
If so, you could post the fstab and we can have a look at how it's being mounted.

Well I'm fine by clicking on the drive to open/mount it, but I wonder why I cannot execute on 12.04/Win-F anymore.

10.04 fstab:

# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).

12.04 fstab:

Thanks

PS: Well it works alike bash script.sh thanks, but not anymore alike ./script.sh

So there is no entry for your NTFS drive in /etc/fstab. When mounted there is probably an entry for it in /etc/mtab, and that should show that it is mounted without execute privileges. That can be changed temporarily with umount and mount (with the correct options, and changed persistently with an entry in /etc/fstab.

But I suggest that you move your executable files to ~/bin unless you use them very seldom and and get along with

bash script.bash

or

sh script.sh

.

Thanks, you are saying adding this:

#UUID=58E0EFA0E0EF831C /media/Win-F ntfs defaults 0 0

would allow to execute with ./script.sh
Well, I might try. Anyway using sh script.sh is the same amount of numbers to type.

[sudodus]

I think your suggestion for /etc/fstab would work (without the # sign), otherwise look at this link

http://askubuntu.com/questions/120233/cant-mount-ntfs-partition-without-root-access

Such a line (specifying read/write permission with rw) should help:

UUID=58E0EFA0E0EF831C  /media/Win-F  ntfs  nls=iso8859-1,rw,umask=000,user  0  0

Remove the # sign, it 'comments the line away', so that it will not be used, only sits there for you to read as a help text 'a comment'.

[MikeCyber]

Yes thanks that works.
I need that also because I call another app(not sh) ./blaa within the script.

[sudodus]

I'm glad it works for you
