I launched this command via SSH on a Debian server:

watch --precise -n 1 top -b -n 1 -p 27330 | tail -n 1 | awk "{print \$9}" >> 27330.log &

After a while I quit my terminal. When I connected again the process was still running. Shouldn't the process be killed? I thought that the only way to keep a process running is to use nohup.

The & at the end of your command makes it run in the background. Therefore, when you quit your SSH session, it will keep running.
