Searching qpdf.exe in CMDs %path% = $env:path

[sneumeister]

On my system I already have qpdf running. It's /bin/ folder is also added to my CMDs %path% variable. To enable the PowerShell-Script Start-BulkRemovePdfPassword.ps1 to find "qpdf.exe" in $env:path, I did the following changes to function Get-QpdfExeFilePath{}....

function Get-QpdfExeFilePath {
###    try { (Get-ChildItem -Path $PSScriptRoot -File -Recurse -Filter "qpdf.exe")[0].FullName }
###    catch { $r = $null }
###    return $r
 # Check, if qpdf.exe is already found in PATH
    $qpdfPath = Get-Command -Name qpdf.exe -ErrorAction SilentlyContinue
    if ($qpdfPath) {
        return $qpdfPath.Source
    }

    # Split PATH-Strings into single paths
    $pathDirs = $env:PATH -split ';'

    # Search single path for qpdf.exe
    $qpdfPath = $pathDirs | ForEach-Object {
        $fullPath = Join-Path $_ 'qpdf.exe'
        if (Test-Path $fullPath) {
            return $fullPath
        }
    }
    # If qpdf.exe not found, return NullArray
    if (-not $qpdfPath) {
        return @()
    }
    return $qpdfPath
}
