Can't make file executable

[kecal.op]

I can't make file executable. When I try to change it through the right click/properities/permissions/allow executing file as program, it seems it's ok for a while and after a approximately a second, the box is empty again. When I try it through terminal, at won't give me any error, but the file still isn't executable.
I try to use google, but I can't find any way to solve this problem.
Thank you for your time and sorry for my english.

When i had the same problem i first changed the ownership and then tried.

 sudo chown $USER <file path>
sudo +x <filepath>

should do the trick.

Hi
No need to change user to make file as execute.
Just do this

sudo chmod +x filename

all the best

I don't use Wubi but are you trying to make a file on the host ( i.e., Windows ) directory executable?

That's not going to work. You can't chmod or chown a Windows file as they have no Linux permission bits to change.

If you're trying to change it to executable so something runs in Wine then you're in luck: http://ubuntuforums.org/showthread.php?t=1747138

I try to do what you say and still it saying it's not marked as executable.
I write this

sudo chown tlauli /media/Data/Download/Minecraft/minecraft.jar

(I have similar problem before, too, it's not fault of minecraft)
write password a then try to change the executability by

sudo chmod +x /media/Data/Download/Minecraft/minecraft.jar

And still nothing. :-\ The case of letters is correct.

EDIT: raja.genupula: Like I wrote in my first post, that comand does nothing.
Morbius1:In windows that file is an "executable jar file". And if I understand correctly to link that you posted, they try to solve a problem with opening the file with wine. But I don't want to open it with wine, just normaly with sun java or opemJDK java.

Same problem with a jar, same culprit ( cautious-launcher ), same solution:

Change the file association:
Right click an *.jar file and select Properties -> Open With -> Add -> Use a custom command > type in:

java -jar

In the "Open With" tab mark the "jar" you added as the default .

See this howto to mount the partition in a way that makes the file executable: http://ubuntuforums.org/showthread.php?t=1604251

Crikey, exe's and jar's don't have to be set as executable to run in Linux. It's a file association problem caused by cautious-launcher.

Here, I'll prove it to you. In a terminal run the following command with the jar file that's not executable:

 java -jar /media/Data/Download/Minecraft/minecraft.jar

It may not run because of something wrong with that jar file but you will not get an error telling you it's not executable.

i'm facing a similar problem and
sudo chmod +x filename
is not helping

That may be - but the original post asks how to make a file executable. I think Wormzy's HowTo is a must read for anyone dual booting.

Either way... it's not worth getting all excited over.
