Powershell command to open After Effects project and run a script on opening

You can use `Invoke-Command` as in Dataclay's cli launcher for  running AE + Templater tasks via command line:

$cmd = "$app_dir\afterfx.exe"
$cmd_args = "$ui_switch $m_switch -r  $PSScriptRoot\$templater_filename"

"
`t`tInvoking Adobe After Effects $v =>
`t`t`t$cmd $ui_switch $m_switch -r `"$PSScriptRoot\$templater_filename`"
"

$scriptblock = {

    param($cmd, $cmd_args)

    $process = New-Object system.Diagnostics.Process

    $si = New-Object System.Diagnostics.ProcessStartInfo
    $si.FileName = $cmd
    $si.Arguments = $cmd_args
    $si.UseShellExecute = $false
    $si.RedirectStandardOutput = $true

    $process.StartInfo = $si
    $process.Start() | Out-Null

    do {
        Write-Host `t`t`t $process.StandardOutput.ReadLine()
    } until ($process.HasExited)

}

Invoke-Command -ScriptBlock $scriptblock -ArgumentList $cmd, $cmd_args

For running scripts from the command line see here:

For opening a project, you could add a app.open command at the beginning of your script.

You would have to construct a powershell script that combs through the files and creates a command string from that. Nothing to do with AE, basically. It's definitely possible, but I'm not versed enough in the Windows Scripting host stuff to provide a quick example. Maybe check the Microsoft site...
