两个简单的用来显示当前主机下uid和gid大于500的帐户信息的script

#!/bin/bash
username="$(awk 'BEGIN {FS=":"} $3 >= 500 && $3 != 65534 {print $1}' /etc/passwd)"
for user in $username
do
id $user
finger $use
printf '\v'
done

或：
awk -F: 'BEGIN{printf "%-20s%s\n", "Username","UID"} $3>=500 && $3!=65534{printf "%-20s%s\n", $1,$3}' /etc/passwd

#!/bin/bash
gidlist="$(awk 'BEGIN {FS=":"} $3 >= 500 && $3 !=65534 {print $3}' /etc/group)"
for gid in $gidlist
do
group="$(awk 'BEGIN {FS=":"} $3 == "'$gid'" {print $1}' /etc/group)"
echo -e "Group=$group $(printf '%13s\t') GID=$gid"
done
