Is it possible to re-write the DOS COPY
command to suppress the "One file(s) copied"
message after copy completion? If so, has
anyone seen this as a free utility?

command.com is resonsible for this message.
Don't know if this will work.
If you can find the actual text message in command.com then use a hex editor and replace the text with spaces or 20 hexa decimal

Beware.
Editing Command.Com will in most case damage it. If you wish to try this make a safe backup copy first.

Why do you need to surpress this message?

Hi,

To suppress this message you can use output redirection to NUL device. For example:

Copy FileName C:\DirName > NUL

Good luck, Igor M

The following Qbasic program will alter the DOS 6.2 version of command.com (54,619 bytes)

OPEN "c:\command.com" FOR BINARY AS #1

S$ = chr$(8) + space$(14)

SEEK #1, &H943A&

PUT #1, ,s$

CLOSE

END

DOS checks to see if the text message "1 File(s) copied" has been tampered with. It only checks the first character of the message though. A long as the "1" is not changed we can change the rest of the text to spaces.
So we are forced to print the "1" to the screen but the "1" can be removed from the screen by printing the backspace character. This is ASCII character 8. Reboot the machine after running the program. Caution this change has not been thoroughly tested but it seems to work.

Here is another version of the program that will let you create a custom message for the "copy" command.

CLS

OPEN #1, "C:\COMMAND.COM" FOR BINARY AS #1

DIM V AS STRING * 22

SEEK #1, &H2199&

GET #1, , V$

IF V$ <> "MS-DOS(R) Version 6.20" THEN
PRINT "Wrong Version"
CLOSE
END
END IF

PRINT V$
PRINT
INPUT "Enter custom message"; CM$

IF LEN(CM$) > 14 THEN
PRINT "Custom message is too long"
CLOSE
END
END IF

S$ = CHR$(8) + CM$ + SPACE$(14-LEN(CM$))

SEEK #1, &H943A&

PUT #1, , S$

CLOSE

END

Make sure the line in config.sys reads:
SHELL = C:\command.com /p

After typing in the program, save it, then run it. Now re-boot.

I want to see the same program in C++ and Pascal so all of us can see just what the college instructors have been teaching. A fair challenge.
