  2. Start-Process EncodedCommand (RedirectStandardError) v5.1

    The following script demonstrates an issue I'm experiencing after moving from PowerShell v4 to v5.1. I make extensive use of Start-Process redirecting StandardError to a file, if this file contains data after execution I can read the file to see what the issue was.

    However, with v5.1 when the launched PowerShell process starts, it makes use of progress output which is on the error stream, so this is redirected to the error file.

    In previous versions of PowerShell this did not happen.

    The output to the script below is as follows:

    Powershell v4

    WARNING: Standard Error
    WARNING: Standard Out
    hello…

  3. Support CamelHumps for tab completion

    CamelHump tab autocompletion would be nice, e.g., cd CH<tab> would expand to CamelHump if a directory by that name existed. This would be nice for any directories in CamelCase.

  4. provide switches for toggles

    admit it, PS is ugly. with the multitudes of loops we have to jump thru to get a desired result, it would be better if you could provide command line switches for common tasks.

    for example, in a select statement, how do you prevent the header from appearing in the output? would be nice if could just do "select -NoHeader …." but you can't.

    that is just one example where I spent 30 minutes looking for a way to display only without headers in a "select" statement. a lot of our searches involves either an object has or has not…

  5. Bug: -Exclude does not work as -Include does in Get-ChildItem, or as expected

    Three folders; d1, d2, d3, with files test.txt and test.mp3 in in d1 and d3.

    '-Include d1' includes only content from d1. Would expect '-Exclude d1' to include the inverse, but it has no effect, it returns all data.

    unless it's run after -Include.

    So '-Include d1 -Exclude d1' returns nothing, as expected.

    Exclude only works as it applies to a file name, not a path.

    So '-Exclude .txt' will exclude all files '.txt' as expected.

    The syntax usage in the help file is identical for both parameters.

    Please fix -Exclude parameter so that it works…

  6. Order is wrong in subsequent execution of loops

    Let's take this simple loop:

    PS C:\temp> for ($a=0; $a -lt 2; $a++ ) {
    >> get-date;
    >> Write-Host "Hello world!";
    >> Get-ChildItem | ft -a;
    >> sleep 1
    >> }

    18 juillet 2018 14:54:47
    Hello world!

    Directory: C:\temp
    

    Mode LastWriteTime Length Name


    -a---- 2018-07-18 14:49 3698 test.txt

    Hello world!
    18 juillet 2018 14:54:48

    Directory: C:\temp
    

    Mode LastWriteTime Length Name


    -a---- 2018-07-18 14:49 3698 test.txt

    As you can see, "Get-Date" and "Hello world!" gets inverted.

    If we remove "ft -a" everything is executed as it should.

    Using While ($true) { ... } does the exact same thing.

  7. Powershell not interpreting spaces correctly

    I am running a powershell script in the Post-Build event in Visual Studio (VS). Here is a simplified version of the command command

    powershell -ExecutionPolicy remotesigned -File "%SampleDir%\update.ps1" "$(ProjectDir)" "$(TargetName)" "$(TargetExt)" "$(Configuration)"

    I want you to understand that I have no control of these macro's $(ProjectDir) ... VS will fill these in.

    To simplify things I've eliminated VS. Here is a script that simply echo's the input given to it. This will show the problem copy the below script to a file called echo-args.ps1

    ===================================

    "The number of parameters passed in is $($Args.Count)"
    $i = 0
    foreach ($arg in $Args)…

  8. Timing Invoke-WebRequest Is Slower in Console than ISE

    We are running a home-grown internet speedtest using a PowerShell script. When running the script in ISE on fast network connections (100mbps+), the Invoke-WebRequest commands run fast enough to reflect 100mbps. However, when the script is run through console, the Invoke-WebRequest is restricted and reports speeds of only 25mbps. How can the console be configured to run with the same resources as ISE?

    FYI, this is not an issue for slower networks. Only fast networks seem to expose the console bottleneck.

  10. write-host -NoNewline parameter is ignored with powershell 5.1

    Starting with WMF 5.0 and WMF 5.1 the -NoNewLine option for Write-Host is essentially ignored.

    Simple example:
    PS C:> Write-Host "no newline test " -NoNewline

    Current Behaviour:
    no newline test
    PS C:>

    Expected Behavior
    no newline test PS C:>

    PS version Table is as follows.

    Name Value


    PSVersion 5.1.14409.1012
    PSEdition Desktop
    PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...}

  11. switch break

    Switch should allow for implied breaks.

    I think it would be useful, if it doesn’t exist to have an additional option, e.g.

    switch -ImplyBreak ($variable) {

    ‘red’ { ‘r’ }
    
    ‘green’ { ‘g’ }

    }

    Where -ImplyBreak would make the code above equivalent to:

    switch ($variable) {

    ‘red’ { ‘r’; break }
    
    ‘green’ { ‘g’; break }

    }

  12. Please modify clause ($var -in 1..3)

    Please modify clause ($var -in 1..3) not to use a list in memory.

    The code becomes unusable when using long ranges like 1..20000000

  13. Powershell write-progress memory leak in remote sessions

    Hello, I have noticed some strange behavior with Powershell when run in a remote session, it seems as if there is a memory leak with write-progress when run in a remote session.

    Take the following code for example:

    $MaxVal = 10000000

    for ($x=1;$x -le $MaxVal;$x++)
    {

    Write-Progress -Activity "Writing a progress event" -PercentComplete ($x / $MaxVal * 100) -Status "$($x / $MaxVal * 100)% complete"
    

    }

    If I run this locally, powershell.exe runs normally and does not take up much memory.

    However, if I run it on the same computer from a remote session (as in, I do an enter-psesssion…

  15. Allow custom message when using the confirm parameter

    Although PowerShell creates a message describing the action about to take place when using the confirm parameter, it would be helpful to have the ability to create a custom message in order to make the dialog more user friendly or provide more detail about what action is about to take place.

  16. Fatal error when using a class when the script is in the folder containing a single quote

    Create a script called "C:\Temp'Test\Test.ps1" and add the following lines:

    Write-Host "Test"
    Class MyClass {}

    Execute this script and you get this error:

    The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047) At line:1 char:1 + & 'C:\Temp''Test\Test..ps1' + ~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : OperationStopped: (:) [], FileLoadException + FullyQualifiedErrorId : System.IO.FileLoadException

    Rename the folder as simply C:\Test and it runs without an error.

  17. Terminating error in if statement script block generates duplicate errorvariable entries

    Consider the following 2 functions (contrived to illustrate the issue).

    function 1error { [CmdletBinding()] Param(); throw "This produces 1" }
    function 2error { [CmdletBinding()] Param(); if($true) {throw "This produces 2"} }

    If you call the function 1error with an error variable, the error variable will act as expected.

    1error -ErrorVariable +1var
    $1var.count #results in 1

    If you call function 2error with an error variable, the error variable will have 2 identical errors.

    2error -ErrorVariable +2var
    $2var.count # results in 2

    PSVersion is 5.1.14393.2189

  18. Using DontShow for a parameter should not hide all CommonParameters from auto-complete

    Using "DontShow = $true" for a parameter has the unexpected side effect of hiding all CommonParameters from auto-complete. The function below demonstrates the issue.

    function Get-Foo {

    [CmdletBinding()]
    
    param(
    [Parameter()]
    [string]
    $Visible,

    [Parameter( DontShow = $true )]
    [string]
    $NotVisible
    )

    process {
    Write-Verbose 'foo'
    }

    }

  19. Merge "Windows PowerShell" and "PowerShell Core", make result default on Windows

    When sending code to someone, I don't want to have to qualify the post with "if it doesn't work, try the other PowerShell...". I know there will be OS-specific modules/commands, but there should not be two code bases for the shell itself, or two product names.

  20. Import-Module does not work with binary modules in exe files

    I've tried putting my commands in an exe module, but could not get this module loaded in PowerShell.

    1) If I try to load my module as-is, e.g. an .exe file I get "The extension '.exe' is not a valid module extension. "

    2) If I create a .psd1 manifest and put RootModule = 'MyModule.exe' there I get Object reference not set to an instance of an object.
