Redirect stdin stdout to multiple files
Hi,
i know how to
a) redirect stdout and stderr to one file,
b) and write to two files concurrently with same output using tee command

Now, i want to do both the above together.

I have a script and it should write both stdout and stderr in one file and also write the same content to another file at the same time.

In other words, both files should contain all stdout and stderr and both files
should be identical, and both files should overwrite any existing files

s1.sh > log1.txt 2>&1

In the above command i want to write the exact ouput to log2.txt at the same time

How to do this?

Thanks
