Probably for very simple use cases, but the real power in parallel really comes from the myriad of switches that enables so much more than what "&" and "wait" could do. Here are a bunch of examples: https://www.gnu.org/software/parallel/parallel_examples.html https://www.gnu.org/software/parallel/parallel_examples.html A fun one I end up using ~monthly or so for various things (usually with more switches added as needed): GNU Parallel as queue system/batch manager # start queue true >jobqueue; tail -n+0 -f jobqueue | parallel # add job echo my_command my_arg >> jobqueue # to start queue for remote execution true >jobqueue; tail -n+0 -f jobqueue | parallel -S ..
