Get-RCLogSummary

‘Sup PSHomies?

Got a lil’ somethin’ for ya… Get-RCLogSummary! As you know I’m a big fan of RoboCopy! I thought I’d share one of the perks of using RoboCopy: the LogFile.

Here’s a list of RoboCopy Logging options, courtesy of ss64.com

   Logging options
                /L : List only - don’t copy, timestamp or delete any files.
               /NP : No Progress - don’t display % copied.
          /unicode : Display the status output as Unicode text.  ##
         /LOG:file : Output status to LOG file (overwrite existing log).
      /UNILOG:file : Output status to Unicode Log file (overwrite)
        /LOG+:file : Output status to LOG file (append to existing log).
     /UNILOG+:file : Output status to Unicode Log file (append)
               /TS : Include Source file Time Stamps in the output.
               /FP : Include Full Pathname of files in the output.
               /NS : No Size - don’t log file sizes.
               /NC : No Class - don’t log file classes.
              /NFL : No File List - don’t log file names.
              /NDL : No Directory List - don’t log directory names.
              /TEE : Output to console window, as well as the log file.
              /NJH : No Job Header.
              /NJS : No Job Summary.

My preference when it comes to logging is to have seperate logfiles instead of appending to one big file. The option /NP is a no brainer, displaying ‘%’ will give you an indication how long it took for that specific file/folder, but who wants that right?It will only increase your logfile size taking more time to parse it down the line. I recently used /NDL and I must say this will keep your logfile footprint small. I did include /FP to still have an idea where the file is being copied from. I’d go with /NDL in combination with /FP when doing a delta-sync. A delta-sync is a robocopy job that will copy the differences once a full-sync has taken place. If the file hasn’t changed robocopy will skip it. Only new and newer files will be copied… Ok enough background, let get scripting shall we? 😛

First I’ll get a list of logFiles and retrieve the first 5-8 lines and the last 10 lines of each file for processing. The LogFileName & array Summary are then passed as parameters to Get-RCLogSummary. I did a select to get the parameters in a certain order. It was a toss up between using [Ordered] Hash or  defining a [PSCustomObject] beforehand. I figured you could minimize the Properties you want by tweaking the $arrRcProperties yourself. last but not least use Out-Gridview or Export-Csv to see the endresult.

I’m working on my pipeline skills, trust me my previous version was more ‘elaborate’, and by elaborate I mean over engineered…

So I guess you’ve noticed that regular expression is missing? Robocopy labels are fixed which is a good thing for me. I’m looking into it…

This regular expression isn’t as easy as it seems… This works, just don’t include /Bytes in your robocopy parameter list. In that case you’ll definitely need regular expression. Version 2.0 I guess…

Hope it’s worth something to you
