[Help-bash] Merge stdout/stderr to a file yet preserve their distinction as well

[Peng Yu]

Hi,

I'd like to pipe stdout/stderr to a file. But I also want them to be
printed to the terminal with them separately as stdout/stderr.

It seems that none of the things mentioned below can satisfy both
requirements. Could anybody confirm whether it is indeed impossible to
satisfy both requirements? Thanks.

cmd 2>&1 | tee output.file
