Drupal File/Directory Permissions

To Start with the General Drupal Practices, Drupal has suggested standard guidelines on what permissions should be set in order for the system to work and to be secure at the same time :

  • Most files should be 644 i.e, -rw-r--r-- 

    chmod 644 filename

  • All directories should be 755 i.e, drwxr-xr-x 

    chmod -R 755 directory-name

  • Files that are intended to be executed using command line should have the executable permission set as 755 i.e, -rwxr-xr-x

    chmod 755 filename


How To Check Permissions

Now, the next question here arises how to check the current set permissions of a file or directory :

    chmod g+ws files

Files Directory Permission
