A big addition to this is to add an entry in /etc/sudoers.d/Update that lets the script below run without a password.

#!/bin/bash
# /usr/local/bin/Update
# This allows updating software by a single common command on all my machines.
 
Logs=~/.Logs/$(date +"%Y/%m/%d")
mkdir -p ${Logs}
LogFile=${Logs}/$(hostname -s)-$(date +"%T.txt")
