    ATTRIB [+R] filename[.ext] 
or
    ATTRIB -R filename[.ext] 
or
    ATTRIB [+A] [-A] filename[.ext] [/S]			[new DOS 3.2]

filename[.ext] may be an actual filename and extension, or include wild cards.

/S causes ATTRIB to modify attributes in the current directory and all of
    its subdirectories. 

The ATTRIB external command without any option will report the current status 
of the attribute(s). It also list the full pathname of each file reported, 
making it a useful alternative to the DIR command in some cases. +R sets and
-R clears the read-only attribute on one or more files in the current 
directory, making it more difficult to delete or modify a file. The read-only 
attribute is discussed in more detail in the NEW_TERMS DIRECTORY topic. The 
archive attribute can also be set (+A) or cleared (-A) on later versions of 
DOS, allowing greater control of files that have been modified and the BACKUP 
and XCOPY commands.
