Aaron LI has ported timeout(1) to DragonFly. It’s a way to run a command with a time limit, and I’m happy to say it is a cross-BSD item, coming from NetBSD by way of FreeBSD.

A running description of activity related to DragonFly BSD.
A minor correction: the timeout(1) was developed in FreeBSD and then imported into NetBSD.
Curious, how much effort / time is needed to port a utility like this?
The porting efforts depends on specific tools.
For example, this specific timeout(1) uses procctl(2), which is not POSIX or BSD standard and is different between FreeBSD and DragonFly and is missing on NetBSD. Also I’m not familiar with this, so it took me about half a day to port this tool.
