    I've got a script that will be executed both from the command line as well as from a scheduler (JAMS). If the script encounters an error, it parses a log file using Select-String, writing that output to the console, which gets captured in the JAMS log file.

    These lines are wrapping in the JAMS log, making them hard to read. I found this hit via Google: ... 56814.aspx. So, I can use that technique to increase the window size and hopefully the output line length.

    I don't want to mess with the end user's console window when he/she is running the script interactively. However, JAMS sets its own Host, which would give me a trigger for my script.

    (Get-Host).UI.RawUI output when run from my PS console:

    [code2=powershell]Name : ConsoleHost
    Version : 2.0
    InstanceId : 728a71ec-7a03-4449-aab3-52ca178d6ec1
    UI : System.Management.Automation.Internal.Host.InternalHostUserInterface
    CurrentCulture : en-AU
    CurrentUICulture : en-US
    PrivateData : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy
    IsRunspacePushed : False
    Runspace : System.Management.Automation.Runspaces.LocalRunspace

    ForegroundColor : DarkYellow
    BackgroundColor : DarkMagenta
    CursorPosition : 0,13
    WindowPosition : 0,0
    CursorSize : 25
    BufferSize : 220,3000
    WindowSize : 220,70
    MaxWindowSize : 220,80
    MaxPhysicalWindowSize : 240,80
    KeyAvailable : False
    WindowTitle : Administrator: Windows PowerShell[/code2]

    Those are nowhere near my screen colors, but the BufferSize and WindowSize are correct.

    (Get-Host).UI.RawUI output from a JAMS Job:

    [code2=powershell]Name : JAMSHost
    Version :
    InstanceId : eb590913-a546-43e8-8155-cb2ddf7a9404
    UI : System.Management.Automation.Internal.Host.InternalHostUserI
    CurrentCulture : en-AU
    CurrentUICulture : en-US
    PrivateData : MVPSI.JAMS.Host.PowerShell.JAMSHostInfo
    IsRunspacePushed :
    Runspace :

    ForegroundColor : White
    BackgroundColor : Black
    CursorPosition : 0,0
    WindowPosition : 0,0
    CursorSize : 1
    BufferSize : 80,120
    WindowSize : 255,80
    MaxWindowSize : 255,80
    MaxPhysicalWindowSize : 255,80
    KeyAvailable :
    WindowTitle ]

    What's throwing me off is the BufferSize and WindowSize certainly look long enough to prevent the line wrapping. For example, if the line length is 255, why do I get this:

    [code2=powershell]UI : System.Management.Automation.Internal.Host.InternalHostUserI

    Do you think Powershell or JAMS is wrapping these lines?

    I suspect it is JAMS since I don't see anything that looks long enough to wrap in a regular PowerShell console. Usually, when using Out-File to write to log files you can use the -Width parameter to prevent this sort of thing. But if you are implying that your script is running in a JAMS PowerShell host, then the wrapping issue is theirs. Not sure if this really helps.

    The following should work for you in either the job source or your PowerShell profile:

    $pshost = get-host
    $pswindow = $pshost.ui.rawui
    $newsize = $pswindow.buffersize
    $newsize.height = 3000
    $newsize.width = 150
    $pswindow.buffersize = $newsize
