I have quite a few "service-like" scripts that I put into the

something. I use 'sleep' for the timing of the wakeup periods.
My question is: How efficient is 'sleep'? I know of other OSes that
just set a timer flag and the process isn't allocated any CPU time
until the timer expires.
I know that creating a service or even using Task Scheduler are more
"proper" ways of doing this, but they are also much more work and
would require a significant learning curve as my background is
embedded systems, not Windows. I know that my lazy way probably has a
penalty, but just how bad is it?
Install Cygwin packages cron plus cygrunsrv to run daemons as services.
Setup cron service by running /usr/sbin/cron-config as elevated admin.
Then use crontab to schedule scripts every so often or at specific times or
days.
Install package and read man pages or see the current package repo:
