Redirect Write-Host statements to a file

Question

I have a PowerShell script that I am debugging and would like to redirect all Write-Host statements to a file. Is there an easy way to do that?

Answer 1

Using redirection will cause Write-Host to hang. This is because Write-Host deals with various formatting issues that are specific to the current terminal being used. If you just want your script to have flexibility to output as normal (default to shell, with capability for >, 2>, etc.), use Write-Output.

Otherwise, if you really want to capture the peculiarities of the current terminal, Start-Transcript is a good place to start. Otherwise you'll have to hand-test or write some complicated test suites.
