[Q] Chmod +x scrip.sh - Galaxy S III Q&A, Help & Troubleshooting

hi all ,
yesterday i just rooted my Galaxy siii and now i am trying to run Ubuntu on it ,
so for the run script in need the x permission but for some reason i cant change the files permissions , i try the command line
su
chmod +x filename.sh
or
chmod 777 or 775 filsname.sh
it don't give an error but after ls -l see that the file still don't get x permission
and still cant run it i try with 2 terminals and withe the commander program but all of them don't success to give the wright permission to the file !
any ideas ? , i search on the forum and the internet find some threads with other devises but with no answer !

Where is the file? You can't change permissions for files on sdcard

You don't need to change it. You just
su
sh ubuntu.sh

put it say permission denied ! , even after su !

Yes I have that issue too. Only on s3 not other phones.
My work around was to run it using script manager. Setting the root permission

i just tried that , didn't work
i tried : like is script :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
and like is executable
and you can see the root " the green thing in the corner "

Works fine for me. Did script manager ask for root?
You have to set root on the properties. Also make sure its set as script not executable
