Bash output all stdout both to console and file

Question

I am trying to output all

stdout

and

stderr

both to console and to a file. I know about

./script | tee somefile

, but that doesn't work for me. I want it to do it automatically, without me piping it from the console. I've tried

#!/bin/sh

exec 2>&1 | tee somefile

echo "..."

but that didn't work. What would be the correct solution?

Answer 1

The classical solution is to add something like this at the top of the script:

test -z "$REXECED" && { REXECED=1 exec $0 "$@" 2>&1 |  tee -a somefile; exit; }
