How to create a script in a DOS batch file to do a loop?

We are copy some files with a batch on a win2k3 server, but some files can't
be copied over becuase they are in use for about 3 minutes. When it is not
in use it can be copied over. So I have created a batch that looks like
this:

copy /y c:\folder1\file1.avi c:\folder2\file1.avi
copy /y c:\folder1\file2.avi c:\folder2\file2.avi
sleep 60
copy /y c:\folder1\file1.avi c:\folder2\file1.avi
copy /y c:\folder1\file2.avi c:\folder2\file2.avi
sleep 60
copy /y c:\folder1\file1.avi c:\folder2\file1.avi
copy /y c:\folder1\file2.avi c:\folder2\file2.avi
sleep 60
copy /y c:\folder1\file1.avi c:\folder2\file1.avi
copy /y c:\folder1\file2.avi c:\folder2\file2.avi
sleep 60

Sleep is a program for the resket that cause the program to pause for 60
seconds. There are more than two files but I figured this would be enough
for the excample. Since each file is 3 minutes long I know the file gets
over written within the 4 atemps. I know DOS has a FOR loop but I read
though the help and could not fivure it out. I know this is proably simple
but I am just not getting it.

Thanks,

Try this:
@echo off
for /L %%a in (1,1,10) do (
xcopy /d /y /c c:\folder1\file1.avi c:\folder2\
xcopy /d /y /c c:\folder1\file2.avi c:\folder2\
ping localhost -n 60 > nul
)

This version will attempt the copy process ten times, with
a pause of about one minute in between. Files that are
already up-to-date won't be copied a second time. Locked
files won't cause the batch file to hang.

 

thanks
