Behaviour depends on your shell. With Bash, for instance: > The shell exits by default upon receipt of a SIGHUP. Before exiting, an interactive shell resends the SIGHUP to all jobs, running or stopped. [...] To prevent the shell from sending the SIGHUP signal to a particular job, it should be removed from the jobs table with the disown builtin (see Job Control Builtins) or marked to not receive SIGHUP using disown -h. > If the huponexit shell option has been set with shopt (see The Shopt Builtin), Bash sends a SIGHUP to all jobs when an interactive login shell exits. https://www.gnu.org/software/bash/manual/html_node/Signals.html https://www.gnu.org/software/bash/manual/html_node/Signals.h...
