MS-DOS Commands 27
Attrib
[drive.]pathname specifies the name of the drive and the full
/^\ pathname of the file you want to reference.
The backup, restore, and xcopy (mcopy) commands use the
archive attribute to control a selective backup/restore/xcopy on
^"^ files that have been modified. You can use the + a and -a
options to select files that you want to back up with the backup
/m switch, or copy with the xcopy (or mcopy) /m or /a
>-v switches.
To display the attribute of a specific file on the default drive, type
the attrib command followed by the pathname of the file. To
/—s print the attributes of all files in a specific directory, use the wild-
card abbreviation *.* in the pathname.
Examples:
The following example gives the file report, txt read-only
permission:
f^] attrib +r report.txt
Suppose you want to use the xcopy command to copy all the files
f"**\ in the default directory of drive A, except for those that have an
extension oi.bak, to drive B. You would type the following:
--■k attrib +a a:*.*
attrib -a a:*.bak
