Output Screen warnings

perhaps simple question

i'm running power shell command -whatif parameter on serveral thousand objects. screen scrolls see various warnings. i'd output warnings further review. how output warnings log file?

thx

that's not simple question.  is, assuming trying capture someting write-warning produce.  there feature request can vote include ability redirect :

https://connect.microsoft.com/powershell/feedback/details/297055/capture-warning-verbose-debug-and-host-output-via-alternate-streams?wa=wsignin1.0

the workaround call cmd.exe /c , redirect output there:

cmd /c powershell.exe -file 'c:\writewarning.ps1' > c:\output.txt

this assumes writewarning.ps1 file has line has this:

write-warning "blah"

alternatively you can use start-transcript if running on supported os transcripts.
