+==== Get list of all non-system Users ====
+I needed a quick 'one liner' to get all non-system users on a Unix system. In this case, non-system was defined as having a UID >= 1000 (common practice) or a shell. The first line defines this.
+This command can be copied and pasted into a terminal as a standard user, and will result in a tab separated list of the user, home directory, shell, and a comma separated list of group memberships
+<code bash>
+getent passwd | awk -F: '($3>=1000)||($7~/(\/bash|\/sh|\/zsh|\/ksh|\/fish|\/tcsh)$/){print $1":"$6":"$7}' \
+| while IFS=: read user home shell; do groups=$(id -nG "$user" 2>/dev/null | tr ' ' ','); printf "%-20s %-30s %-20s %s\n" "$user" "$home" "$shell" "$groups"; done
