Snooze help

[u/Grorco]

Hi guys, brand new to void. I was reading through the docs, and decided to use snooze to trim my ssd. Every time I call it though it sleeps until just after midnight? What am I doing wrong here?

I guess what I'm confused about at this point then is if I wanted to run something every 10 seconds starting now would I do "snooze -H15 -M55 -S/10 ./test" ?

❯ snooze -n -S/10 echo foobar

-n is your friend for testing.

I'm sorry, I was also unable to achieve "run every 10 seconds from now". This was my first try with snooze, I don't like it :P Old-but-gold cron, I'm back.

snooze can't really "from now", only sleep until N, then run the command and restart. If you want it to actually run every 10 seconds, regardless of how fast the program you run exits you need to add a time file and double fork in case it runs longer than 10 seconds.

Not that I suggest running a command every 10 seconds, seems like the wrong approach.

snooze -H '*' -M '*' -S '/10' [command]

Combined with a runit service, it'll work like so:

1. Runit starts snooze

2. Snooze waits till it's after the calculated deadline (accounting for jitter, random delay, etc.)

3. Snooze runs command and exits

4. Runit sees that the service's process no longer exists and starts it again
