I know there are several questions and answers about this - I tried them all - none of them worked for me.

How do I do the equivalent of this (which works in cmd) in a PowerShell command?

for %f in (*.mp4) do "C:\Program Files\DVR-Scan\dvr-scan.exe" -i %f -d events/ -tc

I tried this:

Get-ChildItem -File | Foreach {"C:\Program Files\DVR-Scan\dvr-scan.exe" -i $_.fullname -d events/ -tc }

And like this:

Get-ChildItem -File | Foreach {"C:\Program Files\DVR-Scan\dvr-scan.exe -i $_.fullname -d events/ -tc "}

And like this:

ls -file | & { "C:\Program Files\DVR-Scan\dvr-scan.exe -i $_.fullname -d events/ -tc " }

So what's the right way to do it?

EDIT: This question is not a duplicate of this one. In the other question they are asking about the equivalent of a Bash command. I am asking about the equivalent of a cmd command. Even if the answers are the same, it is not the same question.

    The first example you have on pwsh looks perfect but you just need the call operator `&` before the path: `Foreach { & "C:\Program.....` – Santiago Squarzon Dec 20 '22 at 21:44
  • You can also use the [`Start-Process` cmdlet](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.management/start-process?view=powershell-7.3) (`saps` or `start` for short) to make it a bit more explicit, which may also make it a bit easier to understand what's going on to others that might look at it later on. – Jesse Dec 20 '22 at 21:54
  • @Jesse, to synchronously execute console applications or batch files and capture their output, call them _directly_ (`c:\path\to\some.exe ...` or `& $exePath ...`), do _not_ use `Start-Process` (or the `System.Diagnostics.Process` API it is based on) - see [this answer](https://stackoverflow.com/a/51334633/45375). [GitHub docs issue #6239](https://github.com/MicrosoftDocs/PowerShell-Docs/issues/6239) provides guidance on when use of `Start-Process` is and isn't appropriate. – mklement0 Dec 20 '22 at 22:27
  • In short, as implied by Santiago's comment: An executable path that is _quoted_ or contains _variable references_ must - for syntactic reasons - be invoked with `&`, the [call operator](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_Operators#call-operator-); see the linked duplicate for details. – mklement0 Dec 20 '22 at 22:29
  • @mklement0 The OP didn't say they needed the output, and to run it synchronously you can use the `-Wait` flag. If you don't want it to open a new window, use the `-NoNewWindow` flag. There are options. – Jesse Dec 20 '22 at 22:39

    @Jesse, the OP asked for an equivalent to the batch-file command given. `Start-Process` cannot provide that equivalent (`-NoNewWindow` makes the process run in the same console, but you won't be able to _capture or redirect_ its output). `Start-Process` has its place, but only in very specific contexts, as explained in the [previously linked issue](https://github.com/MicrosoftDocs/PowerShell-Docs/issues/6239). – mklement0 Dec 20 '22 at 22:44
