Calling Patch.exe from Powershell with p0 argument - powershell

Question

I'm currently trying to patch some files via PowerShell using Patch.exe
I am able to call the exe using the '&' command, but it doesn't seem to be reading my p0 input. I'm not an expert on PowerShell and any help would be appreciated!
here is what I am calling in PS:
$output = & "$scriptPath\patch.exe" -p0 -i $scriptPath\diff.txt
My error reads:
can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
Which I can emulate by leaving out the p0 parameter on my patch file from commandline.
Here are some alternatives I've already tried:
#$output = & "$scriptPath\patch.exe" -p0 -i "$scriptPath\diff.txt"
#CMD /c “$scriptPath\patchFile.bat” (where patchFile.bat has %~dp0patch.exe -p0 < %~dp0diff.txt, seems like powershell reads < as 0<, so there is an error there I think)
#GET-CONTENT $scriptPath\diff.txt | &"$scriptPath\patch.exe" "-p0"
#GET-CONTENT $scriptPath\diff.txt | CMD /c “$scriptPath\patch.exe -p0”
Thanks!

Answer 1

Try:
$output = & "$scriptPath\patch.exe" -p0 -i "$scriptPath\diff.txt"

Answer 2

Patch.exe started in the wrong context and I solved this by using Push-Location / Pop-Location
Here is what my code looks like now
Push-Location $scriptPath
$output = & "$scriptPath\patch.exe" -p0 -i "$scriptPath\diff.txt"
Pop-Location
Keith also mentioned in one of his comments that you can use:
[Environment]::CurrentDirectory = $pwd
I have not tested this, but I assume it does the same thing (Keith is a powershell MVP, I am just a student).
