ATTRIB
Set or display the ARCHIVE or READ-ONLY attributes on a file
See also <BACKUP> <XCOPY>
COMMAND TYPE: External VERSION: 3.0 and up
USE: ATTRIB [+R|-R][+A|-A][d:][path] [filename][/S]
+R sets the file attribute to READ-ONLY.
-R removes the READ-ONLY file attribute, allows updating of the file.
+A sets the archive bit.
-A resets the archive bit.
d: path filename specifies the file whose attributes will be changed.
(wildcards may be specified)
/S to process all files in the specified directory and its
subdirectories. (This switch is valid for DOS 3.3 and later
versions).
EXAMPLE: ATTRIB +R HELP.COM
The above example sets the file 'HELP.COM' to a READ-ONLY status. The
archive attribute is set whenever a file is modified, and is used by
<BACKUP>, <RESTORE> and <XCOPY> to determine whether to process files based
on their "modified" status. Other non-MSDOS backup programs also may
examine this attribute. Backup and copy programs may or may not
remove the archive bit, depending on settings.
