Using tee-object with the output from an exe

I'm trying to record the output of yt-dlp to both a log file and see that output on screen. I thought tee would let me do that. I have (yt-dlp something) *>&1 | tee filename.log. It attempts to write the log file only after yt-dlp returns. Plus, nothing appears in the meantime. Do I have something wrong in my PowerShell code?

    What happens if you remove the parentheses surrounding the "yt-dlp something"? Putting that inside parentheses will cause yt-dlp to run to completion (just as any code would because those parens say "do this first") before anything else happens.

    It was passing the rest of the line to yt-dlp. Or at least from what I could see. yt-dlp was complaining about a parameter it didn't know: tee.

    Try using an explicit reference to the EXE file. For example (this works):

    PS C:\windows\system32> .\ping.exe | tee c:\junk\x.txt

    I don't know why it seemed to be passing all that to yt-dlp. I took the parentheses out and it worked.
