viruses per se, don't really apply to unix (there are trojan horses, etc, that can do a great deal of damage though).

here is some snippet from a pdf found on the above site:

" The UNIX operating system is a secure environment, relatively unaffected by computer viruses. The DOS and Windows environment, however, is different. DOS computers have no security and are very susceptible to virus infections. Because DOS system viruses don't affect UNIX systems, you might ask: “Why
should I be concerned?”

One reason for concern is that DOS- and Windows-based computers are rapidly appearing on the Internet-and most of these computers use the Internet for file transfer. A UNIX server might still harbor DOS system viruses and, while not itself affected, can pass them on to numerous DOS- and Windows-based clients. Rather than trying to block viruses at each DOS- and Windows-based computer connected to a UNIX system, you can install the VirusScan for UNIX software and use it as an efficient centralized solution. "

Cheers!
Vishnu.

mcopy(1)						      General Commands Manual							  mcopy(1)

NAME
mcopy - mtools utility to copy DOS files to and from a UNIX operating system SYNOPSIS
mcopy [-mntv] sourcefile targetfile mcopy [-mntv] sourcefile [sourcefiles...] targetdirectory OPTIONS
Preserves the file modification time. Specifies that a warning is not issued when an existing file is specified as the target file. If this option is not specified, the mcopy command verifies whether or not to overwrite an existing file. Specifies a text file transfer. Line terminators are converted to the appropriate format. Specifies verbose mode. The new file name is displayed if the name supplied is invalid. DESCRIPTION
The mcopy command copies the specified file to the named file, or copies multiple files to the named directory. The specified files or directories can be either DOS or UNIX files. If the file is a text file line terminators are converted to the appropriate format. Using a drive letter designation on the DOS files such as 'a:' determines the direction of the transfer. A missing drive designation indi- cates a UNIX file whose path starts in the current directory. DOS subdirectory names that contain the '/' or '' separator are supported. If you use the '' separator or wildcards, you must enclose file names in quotes to protect them from the shell. The mcd command can be used to establish the device and the current working directory (relative to DOS), otherwise the default is A:. Not all UNIX file names are supported in the DOS world. The mcopy command may have to change UNIX names to fit the DOS file name conven- tions. The following table shows some examples of file name conversions: ----------------------------------------------- UNIX name DOS name Reason for the change ----------------------------------------------- thisisatest THISISAT file name too long file.stuff FILE.STU extension too long prn.txt XRN.TXT PRN is a device name .abc X.ABC null file name hot+cold HOTXCOLD illegal character ----------------------------------------------- RESTRICTIONS
The following restrictions exist: Omitting the destination directory is not supported. Using the plus (+) operator is not supported. Using a drive letter designation on DOS files is required with this command only, not with other mtools. EXIT STATUS
The following exit values are returned: Success. Failure. ENVIRONMENT VARIABLES
The following environment variables affect the execution of mcopy: If set, this variable names the file that contains the name of the cur- rent mtools working directory as established by the mcd command. If this variable is not set, the file $HOME/.mcwd is used. FILES
Contains the name of the current mtools working directory as established by the mcd command. If this file does not exist, the default mtools working directory is A:. Executable file SEE ALSO
Commands: dos2unix(1), mcd(1), mdiskcopy(1), mread(1), mtools(1), mwrite(1), unix2dos(1) mcopy(1)
