How do I hide "Extra File" and "100%" lines from robocopy output?

Just noticed you are missing a /NC there.

/NC: No Class - don’t log file classes.

Class files are... What does robocopy mean by tweaked, lonely and extra?

So I'd try: robocopy "$liveRepoLocation" "$cloneRepoLocation" /MIR /MT /W:3 /R:100 /NP /LOG:"$backupLogLocation\BackupKiln.txt" /NC

My bad. Didn't see you had already mentioned trying /NC

I've tested here. It seems that the /MIR option ignores the logging options. Also /MT messes it up, adding the 100%.

The only way I got working was

D:\robocopy>robocopy source destination /MIR /W:3 /R:100 /NS /NC /NFL /NDL /NP /LOG:log.txt".

*It actually works with /MIR. But you have to specify /NFL and /NDL.* Don't know if that's acceptable for you.

If you try /MT, it will still show the silly 100%

I know the question was about Robocopy but I think you should give RichCopy a try http://technet.microsoft.com/en-us/magazine/2009.04.utilityspotlight.aspx

Here's the command line:

richcopy "D:\robocopy\source" "D:\robocopy\destination" /P /QO /QP "D:\robocopy\report.log" /UE /US /UD /UPC /UFC /USC /UPR /UET

It starts RichCopy's GUI and closes when done.

And here's the log

28/11/2012 11:35:19,0,Copy start,

28/11/2012 11:35:20,0,Source path : D:\robocopy\source,

28/11/2012 11:35:20,0,Destination path : d:\robocopy\destination,

28/11/2012 11:35:20,0,Source file count : 12 files,

28/11/2012 11:35:20,0,Copied file count : 13 files,

28/11/2012 11:35:20,0,Purged file count : 1,224 files,

The /XX option excludes the extra files from being listed. Perversely, this option is listed in File Selection options, not Logging. It is the opposite of the /X logging option, I guess.

I think this may work:

robocopy sourceDir targetDir *.* /njh /njs /ndl /np | find /v "*EXTRA File"

So just pipe the output to "find" with the /V for excluding lines which contain the specified text "*Extra File".

how about using the switches

 /MIR /MT /W:3 /R:100 /NFL /NDL /NP 2>&1 | findstr /v /L /C:" * EXTRA " | findstr /v /L /C:"100%%" > "log file name with or without path"

so you have

robocopy "$liveRepoLocation" "$cloneRepoLocation" /MIR /MT /W:3 /R:100 /NFL /NDL /NP 2>&1 | findstr /v /L /C:" * EXTRA " | findstr /v /L /C:"100%%" > "$backupLogLocation\BackupKiln.txt"

• the double %% is required to have a % in the search string
• the 2>&1 redirects the stderr stream to stdout because some messages are written to stderr and we want to capture those lines like the /LOG switch does.
• the 2 findstr commands with the /v switch finds all lines that do not contain the search string
• the > "log filename" redirects the final output to your log file. If you would normally use /LOG:+ then use >> "log filename" instead

Notes: if you are using this in a powershell script, like you seem to be, you need to use findstr instead of find like you can in a .bat or .cmd file. Note the /L and /C: are not supported by find but for the find command they are not required.
