To stop GNU Parallel today you need to send TERM to make it stop starting new jobs followed by another TERM to kill the running jobs.
I am considering changing that to send HUP to stop starting new jobs and TERM to kill running jobs. This will make it easier to kill GNU Parallel: $ bash -c 'parallel -j1 sleep ::: 111 222' & # This would then kill the process group with bash and parallel $ kill -TERM -$! It will make it incompatible with previous versions. What is your opinion? /Ole
