问题
I'm using robocopy to only sync only newer file, but I also need to get the file name being copied.
I've to further use copied file name to make a entry in a some other file.
I wasn't able to found switch, which only displays copied file name, any powershell script of batch file will also be fine.

This function parses all the RoboCopy text output and outputs that as a nice object.
Use it like this:
$RoboCopyOutput = robocopy $source $destination /ROBOSWITCHES
Parse-RoboCopyOutput $RoboCopyOutput
Or this:
Parse-RoboCopyOutput (robocopy e t /s)
(Which shows the error handling)
I can't claim all the ninja regex skills as my own: I found something on this online a few years ago and have expanded it over time. Sorry but I can't find the original article now, or I'd post a link to that.
My RoboCopy version check only looks for the versions that I encounter in my environment and is not exhaustive, so watch out for that. It should be easy enough to find out your version's date format and add it to the switch statement.
Function Parse-RoboCopyOutput ($RoboCopyOutput)
{
#Get RoboCopy version info to determine the date format
switch ((Get-Command robocopy).FileVersionInfo.ProductVersion)
{
{$_ -eq 'XP027'} {$RobocopyDateFormat = 'ddd MMM dd HH:mm:ss yyyy' ; break} #Vista / Windows 7 / Server 2008
{$_ -eq '6.2.9200.16384'} {$RobocopyDateFormat = 'dd MMMM yyyy HH:mm:ss' ; break} #Windows 8
{$_ -eq '6.3.9600.16384'} {$RobocopyDateFormat = 'dd MMMM yyyy HH:mm:ss' ; break} #Windows 8.1
default {throw "Unknown robocopy version."}
}
#Find the line numbers of the '----' spacers in the robocopy output
$null,$HeaderStart,$HeaderEnd,$FooterStart = $RoboCopyOutput | Select-String "----" | Foreach-Object {$_.linenumber}
#Create the object to store all the parsed robocopy output information

user182904,
I have revised my answer to suit your requirements.
Try the following cmd file.
1) It will create a log file from robocopy with just folders\files copied.
2) It will then strip that log file to just the files copied.
@echo off
rem source folders for robocopy
set source="c:\test\files"
set destin="c:\test\files2"
rem logfile names
set sourcelogfile=log-from-robocopy.txt
set destinlogfile=log-just-files.txt
rem robocopy command to output files copied
robocopy %source% %destin% /e /LOG:"%sourcelogfile%" /NP /NS /NC /NDL /TEE /NJH /NJS
rem for loop through robocopy output and stip it down to just file names into new logfile
for /f "tokens=*" %%i in (%sourcelogfile%) do (
for /f "delims=" %%f in ("%%i") do (
echo %%~nxf >> %destinlogfile%
)
)
rem end of code
You can add your options to the Robocopy line, but you will need the options added at the end of that line, to output a log file that the rest of the script will parse.
Hope that helps.
