How to 'chmod' on an NTFS ( or FAT32 ) partition?

I am a beginner on ubuntu 11.10, I want to execute some program named ./Pro but when i try:

$ ./Pro

I get the following error:

$Bash: ./Pro : Permission Denied.

When I try to change the permissions, by running: $sudo chmod +x Pro, nothing changes! In fact when I do $ls -l Pro the result is:

$-rw------- 1 hafez hafez 7251 2012-03-19 07:44 Pro

How can I run my file?

Add to your question that you are a ROOT user. For a beginner I find it odd that you would go directly to using ROOT. — Luis Alvarado, Apr 13, 2012 at 18:32
check the permissions of the directory you are in! (so cd .. and then ls -l|more) — Rinzwind, Apr 13, 2012 at 18:39

Check the output to the following command mount | grep -i nexec I think your filesystem is mounted with a noexec option.

From the man page:

noexec Do not allow direct execution of any binaries on the mounted filesystem.

To solve this (until next reboot)

mount -o remount,exec your_filesystem

To make it survive a reboot, you'll have to edit /etc/fstab.

right click in the file -> permissions -> allow executing fila as a program =)

in command line: try with sudo!

sudo chmod +x Pro

Did you try the graphical way? The first solution I told you. If it not work, make sure that nobody more (program or human) has the file in his possesion.

To know if the file are opened or in posession by one program, execute in a terminal: lsof | grep "filename" without the quotes if something is in the output, then the file is possesed by this program. So you have to close this program/procces before changing the permissions. Are I explained well? =)

Try:

chmod a+x Pro

Or, for fun:

chmod 755 Pro
