Logging

When you're looking for logging the output from a detached screen, you have to specify -L option, but also a config file if you do not want that your logfile is truncated or incomplete due to unexpected behavior source.

conf.log

logfile result.log
logfile flush 1
log on
logtstamp after 60
logtstamp string "[ %t: %Y-%m-%d %c:%s ]\012"
logtstamp on

Run example:

screen -c ./log.conf -L -dmS test python3 benchmark.py

Alternative

Create a screen screen -S test, then attach current terminal to the created screen screen -x test, then run your command inside
