attrib +r autoexec.bat - This would make the autoexec.bat so it cannot be modified until the read only attribute is taken off.

attrib +h config.sys - This would make the config.sys hidden so to the average user this file would not be existent however if the attrib command it typed alone "attrib" this will show any hidden files.

attrib -h config.sys - This command will do the apposite of the above command. Instead of hiding the file it will unhide the file if hidden.
