in reply to sleeping for a minute

And here's a non-perl suggestion:

If your script runs on a linux or unix-like system, you can create a cronjob, which runs your script every minute.

In Windows you could set up a scheduled task to do so.

I'd prefer running the script every minute (by cron or scheduled task) than having it run continuously and sending it regularly to sleep for a minute.

    Loading perl every 60 seconds seems like a lot of overhead.

    A periodic (but less frequent) watchdog might be the way to go if you wanted extra reliability.

      I see bot403's point, but I think more along these lines, too. I'd rather just idle for a bit instead of have to start from scratch each time.

    Why would you prefer that? Just curious...

      1. In case it dies.
      2. In case it has a memory leak.
      3. In case someone kills it purposely or accidentally
      4. So you dont have to install it to run when the system starts up.
      5. Because making a true daemon or windows service that *behaves well* is a minor PITA
      6. To have more fine grained control on when and how often it runs (day of week, day of month, hours, etc)

      bot403 listed the reasons I was thinking of (even a few more).

[stevieb]: choroba my GPS home device is done, at least prototype v1 is. I'm just making sure all of my code does what it says now
[stevieb]: I test/prototype code on my Pi, then I migrate it over to Arduino when it's ready (if that's a better platform for what I'm doing). The whole RPi stuff was for learning at first, then it snowballed. I'm just trying to get my in-house CI...
[stevieb]: ...done, which obviously requires a specific hardware setup.
[stevieb]: I don't write tests for the lower-level distributions (ie. ICs, sensors etc) within those distributions, I have all tests in a master distribution which encompasess all of the sub-modules
