Get IP from host
I just wanted a simple DNS request. Because host and nslookup commands are not on all systems, we use getent instead. Thanks aulem for that tip.

This is an alternative to #9131. ffmpeg didn't work on my .au files, though it did on the .wav ones. Also useful if you don't have ffmpeg but do have sox. Handily, sox already reports in seconds (decimal).

Run a command if file/directory changes
Example: $ runonchange /etc/nginx nginx -t Ignores vim temp files. Depends on 'inotify-tools' for monitoring of file changes. Alternative to tools like 'entr', 'watchr'.
