SU password

[geffers]

I've been having problems with changing file permissions.

sudo chmod doesn't give any errpr messages but doesn't change any file permissions.

If I enter su the raspberry password doesn't work, is there a separate one for super user.

sudo chmod a+x filename

works for me ok, plus

./filename to get it to execute

discussion on root password here:-

su does it for me.

sudo chmod doesn't give any errpr messages but doesn't change any file permissions.

At a guess, you are attempting this on a FAT (or NTFS) filesystem, which is not capable of storing POSIX file permissions.

The permissions on these filesystems are faked based on the umask= (or fmask= and dmask=) mount options.

If you are trying to grant write access, then you probably do not want to change the permissions anyway, but instead change the ownership with the mount option uid=pi.
