basically, root privilege is not available for users.

why do you need root privilege? why do you want to copy files to that directory?

Hi ^^ 

I want to change the system font. ( in Application )

In order to change the system font is put the file in the following path.

PATH : /usr/share/fonts  

 

TEST : sdb root on 

before : TizenSans.TTF

After : HMFMOLD.TTF

 

The SDB can have 'root' privileges, but the Application is 'app' privileges. So, permission denied.

Is there another way?
