Revision 94a4a4fe4c696413932eed8bdec46574de9576b8 authored by Guillaume Nault on 08 March 2022, 22:15:03 UTC, committed by Jakub Kicinski on 10 March 2022, 04:23:32 UTC
When using "run_cmd <command> &", then "$!" refers to the PID of the
subshell used to run <command>, not the command itself. Therefore
nettest_pids actually doesn't contain the list of the nettest commands
running in the background. So cleanup() can't kill them and the nettest
processes run until completion (fortunately they have a 5s timeout).

Fix this by defining a new command for running processes in the
background, for which "$!" really refers to the PID of the command run.

Also, double quote variables on the modified lines, to avoid shellcheck
warnings.
