1) Go to the directory where the wien2k codes are installed

2) If you are the owner of the files:

chmod -R ugo+r,a+X *
This gives reading permission to the owner (you) and sticky execution
permissions to anybody. Your "-rwxrwxr-x" refects that this is tour desire,
The -R option works recursibely on the directory you are in.

3) You can modify the owner:group propietary of the files with chown.
   Current linux installments tend to create ${USER} and ${GROUP} equivalent,
   but this is not the best decission if you have coworkers and students
   that could share your codes and scripts.
   You will need root permisions (or be a sudoer) to change owner:group
   of files.

Good luck,
