'tee' STDERR output (ksh)
Hi everyone,
KSH question: I know you can 'tee' STDOUT to have the output go to multiple targets; can you do the same with STDERR?
For example:
ls |tee /tmp/file.txt
Will redirect STDOUT to both the screen and the '/tmp/file.txt' file. Is there a way of doing the same thing for STDERR? Ultimately what I'd like is to send STDOUT to the screen and STDERR to both the screen and a debug file.
Thank in advance for any help you can provide.
