powershell putting linebreaks inappropriate places in output


I have a PowerShell script, but some of the output gets cut at an arbitrary point before continuing on the next line. This is incredibly annoying.

For example, I can use Write-Host and the line will continue on as long as I want it (note, that is running in Team City and Team City adds some prefix information - however the same effect can be observed piping the output to a file):

[10:04:45] [Step 5/7]  - Found Windows Service at G:\TeamCityData\TeamCityBuildAgent-1\work\282b8abc9094651e\Artefacts\windows-services\WindowsService.Dummy\WindowsService.DummyService.exe

Other times, the output will seem to artificially truncate at an arbitrary point, like it was wrapping within a window (which isn't there).

So, this line:

Copy-Item -Path $fullSourcePath -Destination $destPath -Recurse -Verbose -ErrorAction Stop

Produces this output in Team City (which adds some prefix information):

[10:04:46] [Step 5/7] VERBOSE: Performing the operation "Copy File" on target "Item: 
[10:04:46] [Step 5/7] G:\TeamCityData\TeamCityBuildAgent-1\work\282b8abc9094651e\Artefacts\windows-services\WindowsService.Dummy\WindowsServi
[10:04:46] [Step 5/7] ce.DummyService.exe Destination: 
[10:04:46] [Step 5/7] \\SERVER001\scheduled-tasks\ProductFolder\Dev\DummyWindowsService\WindowsService.DummyService.exe".
[10:04:46] [Step 5/7] VERBOSE: Performing the operation "Copy File" on target "Item: 
[10:04:46] [Step 5/7] G:\TeamCityData\TeamCityBuildAgent-1\work\282b8abc9094651e\Artefacts\windows-services\WindowsService.Dummy\WindowsServi
[10:04:46] [Step 5/7] ce.DummyService.exe.config Destination: 
[10:04:46] [Step 5/7] \\SERVER001\scheduled-tasks\ProductFolder\Dev\DummyWindowsService\WindowsService.DummyService.exe.config".

How do I stop this absurdity? I want the output to render line breaks correctly at the end of the line, not in the middle of a filename.

UPDATE

A comment below suggested this was an issue with the way TeamCity was capturing the output. However, the same issue happens if I do a similar command directly in a PowerShell console and pipe the output to a file.

The command:

copy-item -Path F:\logs -Destination .\ -Recurse -Verbose *> F:\logs\copy-item-output-1.txt

Produces output like this:

Performing the operation "Copy File" on target "Item: F:\logs\20161103-140649-ProductName.Program.log 
Destination: F:\Destination\1234567890abcdefghijklmnopqrstuvwxyz\this-is-a-long-path-name-to-show-wrapping-issues-with-copy-it
em\logs\20161103-140649-ProductName.Program.log".

As you can see, it also splits the file path across lines, even although it is being sent to a file, not the console window.


Solution

  • The following solution (more than 10 years old so there might exist a smarter way recently?) works in both PowerShell and PowerShell ISE:

    $pshost = get-host
    $pswindow = $pshost.ui.rawui
    $newsize = $pswindow.buffersize
    ### do not change $newsize.height
    $newsize.width = 3000               ### [int] type; max. value unknown at present
    $pswindow.buffersize = $newsize
