Question

I find unxutils and and gnuwin32 Packages don’t have this command…

Answer 1

On systems where I don’t have a watch, I often use an infinite loop (you could also write it as an alias)

I’m using Bash syntax here, but you can surely do something similar on your platform:

while true; do my-thing-to-watch; sleep 1; done

And, for convenience, one can wrap it into a command which reuses either $0 or $@ depending on your platform.
