Help with using grep command with copy command

Hi, im taking an entry Unix class, and as part of my lab assignment I have to copy all files in the /home/david/lab3 directory that have the file extension .save to your lab3/temp directory. I'm having trouble getting the grep to do anything worth while

I've been trying to do:

cp /home/david/lab3 /home/user113/lab3 | grep '.save'

and havnt gotten it to work yet. Am I using the right context? I really am at a loss here. Also, when I try to run "grep '.save' in the /home/david/lab3 directory i dont get any output, and i have to ctrl+d to get back to a prompt. Any help would be appreciated, I have to finish this lab by 6:30pm EST.

edit: I'm using the Bourne shell.

NAME
mcopy - copy MSDOS files to/from Unix SYNOPSIS
mcopy [ -tnvm ] sourcefile targetfile mcopy [ -tnvm ] sourcefile [ sourcefiles... ] targetdirectory DESCRIPTION
Mcopy copies the specified file to the named file, or copies multiple files to the named directory. The source and target can be either MSDOS or Unix files. The use of a drive letter designation on the MSDOS files, 'a:' for example, determines the direction of the transfer. A missing drive des- ignation implies a Unix file whose path starts in the current directory Mcopy will allow the following command line options: t Text file transfer. Mcopy will translate incoming carriage return/line feeds to line feeds. n No warning. Mcopy will not warn the user when overwriting an existing file. v Verbose mode. m Preserve the file modification time. If the target file already exists, and the -n option is not in effect, mcopy asks whether or not to overwrite the file. MSDOS subdirectory names are supported with either the '/' or '' separator. The use of the '' separator or wildcards will require the names to be enclosed in quotes to protect them from the shell. The mcd command may be used to establish the device and the current working directory (relative to MSDOS), otherwise the default is A:/. SEE ALSO
mcd(1), mread(1), mwrite(1) BUGS
Unlike MSDOS, the destination directory may not be omitted. The '+' operator (append) from MSDOS is not supported. No other Mtools command requires the use of a drive letter designation on MSDOS files. local MCOPY(1)
