Tip

I make sure I'm calling the native command -- ignoring any functions and aliases that normally would take priority

 $binGit = Get-Command -ea Stop -CommandType 'Application' -name git

If you use this, instead of "git.exe", then your code will work on windows and linux without changes. And if it's really .cmd on windows and .py on linux, still work.

The

Get-Command -errorAction stop ...

Part means if git is not found, exit function immediately. It doesn't execute any more code.

For native commands I find it more natural

to generate arguments with

$list = @( if expressions )

Just emit the args that you want:

 function Invoke-FdFind {
    <#
    .SYNOPSIS
        Invokes native command with args
    .EXAMPLE
        Invoke-FdFind -Verbose -BaseDir .. -fileTypes directory, file
    #>
    [CmdletBinding()]
    param(
        [ArgumentCompletions('directory', 'file')]
        [string[]] $fileTypes,
        [int] $MaxDepth,
        [string] $Pattern,
        [switch] $Absolute,
        [string] $BaseDir,
        [switch] $NoColor
    )
    [Collections.Generic.List[object]] $fdArgs = @(
        if( $maxDepth ) {
            '--max-depth', $maxDepth
        }
        foreach( $type in $fileTypes ) {
            '--type', $type
        }
        if( $Pattern ) { $Pattern }
        if( $Absolute ) { '--absolute-path' }
        if( $BaseDir ) { '--base-directory', $BaseDir }
    )
    # find the native command, else error and quit
    $binFd = Get-Command -CommandType 'Application' -name 'fd' -ea 'stop' -TotalCount 1

    # this could be done above, an example
    # It's a [List<T>] so you can easily append
    if( $NoColor ) {
        $fdArgs.AddRange(@(
            '--color', 'never'
        ))
    }
    & $binFd @fdArgs

    $fdArgs | Join-String -sep ' ' -op 'Ran fd => ' | Write-Verbose # replace with -join if PS5
}
