Why I am getting no out-file or no content on the text file?

Question

Power shell script to run a batch file:

start-Process C:\Test.bat |
Out-File C:\test.txt

when I check the text.txt file is empty?

Don't use Start-Process if all you need is to run a program in the more or less default way.

C:\Test.bat | Out-file C:\Test.txt

should work fine, although you most likely lack write privileges on C:\ so that's perhaps not the most useful path to use.

Start-Process does not redirect standard output by default. You have to tell it to do so:

Start-Process -FilePath .\test.bat -NoNewWindow -Wait -RedirectStandardOutput ".\test.txt"

Note, that this will not capture errors. If you want them too, add -RedirectStandardError ".\test-stderr.txt". This must be a different file than the one that you used for -RedirectStandardOutput.
