  1. copy-item progress

    Add an optional switch to show the progress of an ongoing copy operation. Could be useful for large operation. Basically replicate as much information as the Explorer does, without the performance graph.

    • Bug: Slow function when setting a parameter to Mandatory and specifying its Type

      There is a bug that causes a function to be called much more slowly than it should if an array parameter has both Mandatory and Type specified. I'm guessing something is causing the system to iterate through the array, so the larger the array, the longer to call the function.

      With both Mandatory and Type specified, it takes a whole second to call a function with a 10MB byte array. If a 1byte array is used, it takes less than a millisecond to call the function. If only one, the other, or neither are specified, then it takes less than…

      • Move-Item's -Verbose causes $ErrorActionPreference to be ignored

        Move-Items's -Verbose parameter causes the global $ErrorActionPreference = "Stop" to be ignored. This is a bug. Here's a repro script:

        BugRepro.ps1:

        $ErrorActionPreference = "Stop"
        Write-Host "ErrorActionPreference is $ErrorActionPreference"
        mkdir folder -ErrorAction SilentlyContinue | Out-Null
        "" > a.txt
        Copy-Item a.txt folder
        Write-Host "About to trigger error"
        Move-Item a.txt folder -Verbose | Out-Null
        Write-Host "If you're reading this, then execution didn't stop!"
        Write-Host "Remove the Verbose paramter and it does stop, like it should."

        • PowerShell StackOverFlowException: get-childitem -path HKLM:\ -recurse -include *Windows*

          PowerShell has a bug in it which causes a "StackOverFlowException" when running the following command:
          get-childitem -path HKLM:\ -recurse -include *Windows*

          It was originally reproduced while looking for something different than:
          Windows

          This is consistently reproducible in latest updates applied of Windows 10 x64 Business and Home, with both PowerShell.exe, and ISE, x86 and standard.

            • Mandatory parameters value is not accessible in DynamicParam block if the value to the parameter is given when prompted.

              Parameter value from param block is not available in DynamicParam block if not passed while calling the function/Script. Here if I set the parameter in param block as it as mandatory the script/function will prompt for the input and the input given is not available in DynamicParam block.

                • Define which as one of standard aliases of Get-Command

                  Users of Unix-like OSs(e.g. macOS & Linux) use the command `which` to know where the executable of a command is.

                  ```
                  $ which code
                  /usr/bin/code
                  ```

                  On the other hand, users of PowerShell uses the commandlet `Get-Command` or the alias `gcm`.

                  ```
                  PS C:\> (gcm code).Path
                  C:\Program Files\Microsoft VS Code\bin\code.cmd
                  ```

                  However, the users of Unix-like OSs have to learn `gcm` if they have to use PowerShell and want to know the place of a command, though they don't if they would like to, for example, change directories and show the contents of files because PowerShell defines the same aliases…

                    • code execution not synchronously when using "| Select-Object...."

                      When using " | Select-Object......" then code execution behave like it's not running synchronously.
                      Example:
                      Get-WmiObject Win32_NetworkAdapter | Where-Object {$_.PhysicalAdapter -eq $true} | Select-Object DeviceID, Name
                      Read-Host "Press key to continue"

                      The result will be printed AFTER the Read-Host command, nut before as you would expect.

                      A workaround is to add " | Out-Host"

                        in this case I have to remove and reinstall an OS while booting from usb stick. But this is only one example - it´s not the first time im seeing this behaviour.

                        In this line the term C is used three times

                        First time as c: (here would be c:\ also possible)
                        Second time as c (neither c: nor c:\ is working here)
                        Third time as c:\ (neither c nor c: is working here)

                        • Order of output not intuitive/ not sequential

                          Example Code:
                          $proc = Get-Process | Select-Object -Property ProcessName

                          $proc[5]

                          "A"
                          "B"
                          Write-Host "$proc[5]"

                          The output of Write-Host precedes the output of the strings beforehand. This is a non-sequential behaviour.

                                • [Bug] IE automation script will no longer work in PowerShell version 5

                                  To be better notified of incoming tickets in our ticket system I developed a script that opens a hidden IE instance:

                                  $ie = New-Object -ComObject InternetExplorer.Application
                                  (I tried the respective registry entry and "$ie = new-object -Com InternetExplorer.ApplicationMedium", no better.)

                                  (This input box is too small.)

                                  After some script statements to log in and navigate to the incoming tickets monitor, I do a

                                  $newcalls = $ie.Document.getElementsByName("callid")

                                  (This input box is too small.)

                                  That's working perfectly fine in PowerShell version 4, but in v5 I get

                                  Exception from HRESULT: 0x800A138A
                                  At <path>.ps1:89

                                  + $newcalls = $ie.Document.getElementsByName("callid")
                                  + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

                                  • join-object

                                    Hello,

                                    Would it be possible to natively have the Join-Object command as explained on the following MSDN blog: https://blogs.msdn.microsoft.com/powershell/2012/07/13/join-object/

                                    Being able to cross data so easily (especially with left join) would really be a plus I think.

                                    thank you

                                    • Add ExportTo-Markdown

                                      Hi

                                      Using Markdown is common nowadays in VCS tools like Git for readme files.

                                      Plus it's handy to get a tabular strcture for better visibility.

                                      Example use cases:
                                      - Get-Process output comparison at different dates and time
                                      - SQL query results in tabular form with column names as headers

                                      So it'd be someInput|ExportTo-MarkDown

                                      • Convert ToBase64 causes excessive memory usage

                                        Converting most files (200 KB+) causes large memory usage. For instance, a 611 KB photo (one found in /Web/Wallpaper/Theme1) takes up 1 GB of RAM in PS.

                                        [convert]::ToBase64String((get-content $path -encoding byte))

                                        • PowerShell Crash Get-NetFirewallProfile when run as service

                                          PowerShell crashes when running "Get-NetFirewallProfile | Select-Object LogFileName" by a windows service. In my case it was check_mk through a monitoring plugin.
