SYS(DOS) UNIX System V SYS(DOS)
Name
sys - transfers the MS-DOS system files from the disk in the
default drive to the disk in the specified drive
Syntax
sys drive:
Description
Usually, you use sys to update your system or place it on a
formatted disk that contains no files. You must type a
drive letter with this command.
If the system files io.sys and msdos.sys are already on the
target disk, they must take up the same amount of space on
the disk as the new system will need. This means that you
cannot transfer system files from an MS-DOS 2.0 disk to an
MS-DOS 1.1 disk; instead, before sys will work, you must
reformat the MS-DOS 1.1 disk with the MS-DOS 2.0 format
command.
The target disk must be completely blank or must already
contain the system files io.sys and msdos.sys.
The transferred files are copied in the following order:
IO.SYS
MSDOS.SYS
io.sys and msdos.sys are both hidden files that do not
appear when you enter dir.
The sys command does not transfer the command.com file (the
command processor). To transfer command.com to the target
disk, you must use copy.
Notes
sys is an external command.
