The one that comes to my mind is crontab, [which can be] replaced by timer units. These are all the POSIX standardized commands: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/ https://pubs.opengroup.org/onlinepubs/9699919799/utilities/ It's also interesting that POSIX specified a job queue environment that nobody seems to use (entry with the qsub command), separate from the simple job system that originated in Bill Joy's C shell. The systemd oneshot service modifier comes to mind as an alternative to qsub.
