How to append date/time to each start-transcript session RRS feed

  • Question

  • Hi!  I know I can't be the first person to want to do this, but how can I add the date/time to each powershell transcript?

    Admittedly I'm a newbie...but here's what I'm coming up with so far:

    (Removed actual prompt, and replaced with ">" for this submission) 

          > $dt=get-date -format s
          > $logname="c:\Users\JustaN\Documents\Logged_PS_Cmds-"+$dt+".txt"
          > start-transcript $logname

          start-transcript : Transcription cannot be started.
          At line:1 char:1
          + start-transcript $logname
          + ~~~~~~~~~~~~~~~~~~~~~~~~~
              + CategoryInfo          : InvalidOperation: (:) [Start-Transcript], PSInvalidOperationException
              + FullyQualifiedErrorId : CannotStartTranscription,Microsoft.PowerShell.Commands.StartTranscriptCommand
    The variable does work (as evidenced below), but how to get it to work with the start-transcript command?

         > $logname

    I was going to stick all this in a .ps1 file once finished.
    I've got to be somewhat close...hints anyone?   Thanks in advance!

    Apologies if this is posted somewhere...I spent an hour or so searching tonight, but was unable to find this exact application anywhere...though like I said, I doubt I'm the first to want to do this!   =)

  • The value of $dt contains a colon character which is not valid for filenames. You need format it correctly. 
    This should work:

    $dt=get-date -format yyyy-MM-dd-hhmm

    Also, please use the code formatting tool when posting code.

    My script would look like 

    $dt=get-date -Format "MM-dd-yyyy"
    Start-Transcript -Path "c:\temp\transcript-$dt.txt"

    Kind regards

  • $dt=get-date -format s
    start-transcript $logname

  • Though the Start-Transcript Cmdlet doesn't say anything about it, that still contains an invalid character that prevents the transcription log from actually being created.

    $dt gets formatted as: 2018-11-28T10:53:57

    That cannot be (part of) a filename because of the colon characters in the time notation.

  • Here is a way around that issue:

    $logname = '{0}\Documents\Logged_PS_Cmds-{1:yyyy-MM-dd HH.mm.ss}.txt' -f $env:USERPROFILE,[datetime]::Now
