| Feb 16, 2024 at 4:48 | comment | added | Mark G. | Just because it hasn't been said yet, but I think it bears mentioning for those who might not be aware: crontab is POSIX. systemd-timers are not. I would hazard a guess that that's probably how the "Cron is guaranteed to be on any Unix-like system" sentiment originates, which I wouldn't say is necessarily wrong in light of this. In any event, POSIX pedants can just claim that systems that don't comply with it can hardly call themselves "Unix-like", since POSIX is meant to represent a lowest common denominator of Unices. | |

@RobertSiemer Actually, one real life case I was recently looking at is using fetchmail (or getmail) to download mail from a server using POP3. But there are dozens of such possible examples.

remove apology, and systemd is likely not as controversial as it used to be

| Apr 23, 2016 at 14:56 | comment | added | larsks | That's quite a list of things you want in an answer. I think maybe you should spend some time learning the tools yourself and see if you can formulate those answers on your own, and if you have specific things you don't understand, ask them here. | |

@Guido I just meant that it is guaranteed to be available for installation. I didn't men to say it was guaranteed to be installed on any given Unix-like system, though this is probably the case most of the time. On Debian, at least, cron has priority important, though it doesn't try very hard to stop me from removing it. The only thing my system has that actually depends on it is munin, which is a little surprising.

| Apr 23, 2016 at 13:52 | comment | added | Guido | "Cron is guaranteed to be in any Unix-like system. That is not going to change." – I would strongly debate this. While historically cron has often been included in the base setup of Unix installations, on most systems today it's simply an arbitrary optional software package among others. In fact, there are several popular cron alternatives around (e.g. anacron, fcron, jobber) which may be preferable to cron. cron's functionality is not essential for a system's operation the way systemd or init is, so if you're concerned about current and future portability, I'd rather not place my bets on it. | |
