How do I output to stdout when calling editor from command line?

I have UE4Editor.exe running tests in a Jenkins step.

How do I get the log to output on stdout instead of a file or a separate console?

-log puts it in a console window or lets me put it in a file, but that’s not helpful for this case.

As far as I can tell there is no way to do this directly.

I had to write to a file using -log=Test.log then use type Saved\Logs\Test.log to send it to stdout.

This is a little late, but I got here first when searching in Google, so hoping to help others find the answer more quickly. You can pass -stdout as an argument to UE4Editor-Cmd.exe instead of -log and outputting the file - not sure why this is not a documented option, but I have successfully used it to get automated tests with the editor to log to standard out and hence to Jenkins.

I’m even later, but this solution only works for me when I pass both the -log and -stdout flags to my game’s executable when I run it from powershell (i.e. if I call MyUnrealGame.exe -log -stdout). Then, a separate terminal window opens up with a live feed of my game’s console logs.

But if I pass only the-stdout flag to the exe, nothing happens and I don’t get to see any console logs.

But thanks for teaching me about these flags @Arukhan :smiley:

I’m using Unreal Engine 5.2, my project’s build type is “Development” and I’m running powershell inside the Windows Terminal in case anyone may find that information relevant.
