Simple tip to redirect all results into a file.

Here is a simple shell that works for that.

#!/bin/bash

exec 1<&-
exec 2 shell_result.txt
exec 2>&1

ls -l
ls fake_data
echo "Done"

It will close standard output/error and open that file descriptors for the file shell_result.txt. As a result, all the following commands’ output will be redirected to the specified file.
