How I can accomplish STDOUT to be to logged in a file (appending), but preserving the flow (leave STDOUT to STDOUT) ?
STDOUT should work transparently, but should be logged also into a file, without messing with "tee" on each command input. Same for STDERR.
Simply, mirror output to file.
What about using the 'script' command...
This will create a file called typescript that records all commands that you input and their respective output.
