As you know, In Linux everything is treated as a file. A folder is also known as directory file denoted by ‘d‘ in the permission section. The below command will set the owner to www-data and group-owner to ubuntu for all files and directories and subdirectories. Use the chmod command to change the permissions for all files, directories, and subdirectories. Note – The permission 755 is good to set for directories but not on files. This set the execute bit on files which is not recommended for any production environments excluded some specific cases. We recommend setting permissions separately for files and directories. Set permissions on files: Set permissions on directories: All done.
