如何在Linux中只选择非系统用户？如何依赖于他们的ID？I need smth like this. Don't pay attention to the date. It's unnecessary
那我现在，该如何继续下去？

# !/bin/bash

now=$(date --date "$(date +"%Y-%m-%d") -2 month" +%F)

for i in $(cat /etc/passwd | awk -F: '{print $1 ":" $3}'); do
        id=$(echo $i | awk -F: '{print $2}')
        name=$(echo $i | awk -F: '{print $1}')
