I wrote a /bash script and to execute it I decided to set all the rights, so I tried

chmod 777 * //I had 3 text files in the directory, so that's ok

Then to check the result I typed

ls -l

But the rights hadn't changed at all.

I haven't got any error messages and it seems strange. I also tried to specify full path, but this hadn't helped.

I also tried to do all of these steps under root

Where may be the problem?

Thank you for help!

ls -la

drwx------ 1 gemma gemma 4096 июля  20 18:00 .
drwx------ 1 gemma gemma 4096 июля  20 16:35 ..
-rw------- 1 gemma gemma  407 июля  20 18:00 buildedfile.out   ;this is what I
                                                               ;need to launch
-rw------- 1 gemma gemma 4096 июля  20 17:21 kernel.bin
-rw------- 1 gemma gemma  350 июля  20 16:59 link.ld

-rw------- 1 gemma gemma 1894 июля  20 17:34 start.asm
-rw------- 1 gemma gemma  457 июля  20 17:20 start.o

That is what ls shows after all I tried

I rebooted PC and problem rose again. But now any of suggested methods doesn't help.

I'm using Linux Mint 13 32-bit. On main disk where this files are located I have ext3, also tried on two another partitions where I have ntfs and FAT32.

buildedfile.out is a terminal app written on C

  • Did you get an error from the chmod command? – Fran Jul 20 '12 at 14:45
  • did you try chmod 777 /path/to/folder/* – user98645 Jul 20 '12 at 14:48
  • Please post the output of ls -la – deppfx Jul 20 '12 at 14:59
  • Try the verbose switch: chmod -v 777 * – Dennis Jul 20 '12 at 15:23
  • You can also try chmod a+x * (or even better chmod a+x buildedfile.out) if that works and you just need to execute a file maybe it's only the 777 thing wich causes trouble :/ – Flinth Jul 20 '12 at 15:25

I had this same problem, the partition I was accessing was an ntfs partition mounted with ntfs-3g (with no permission support by default), and it took a while for me to remember that.

I would expect chmod to give me some warning, but it didn't just like in your case.

I know there is an option on fstab when using ntfs-3g to make it possible to set permissions in an ntfs partition as described here.

I hope it helps.

    That can happen on a vagrant box as well which was the case for me. So, I changed the permission of the directory from within host system. Et voila, permission granted on virtual machine. Thanks for the hint. :) – Arvid Mar 20 '17 at 15:49
  • tldr: mount -o permissions /dev/... – phil294 Jun 7 '18 at 4:45

Try: sudo chmod -R -f 777 *

I think that can be a permission issue.


Are you sure your filesystem is not mounted read only ?

Type mount command to check. if there is ro in the mount options, you need to remount your filesystem with the following command :

mount -o rw /dev/ /mountpoint

You can also check which user owns the shell script.

If it's not "gemma" it could be the cause of the problem.
