批量创建账号脚本

密码通过uuid随机生成八位， 用户名 seq -w 10 生成 01-10

#!/bin/bash

. /etc/init.d/functions

USER="oldboy"
PASSFILE=/tmp/user.log

for num in `seq -w 10`;do
        PASS=`cat /proc/sys/kernel/random/uuid|awk -F '-' '{print $1}'`
        useradd $USER$num &>/dev/null
        echo $PASS | passwd --stdin $USER$num &>/dev/null
        echo -e "user: $USER$num	passwd:$PASS" >>$PASSFILE
        if [ $? -eq 0 ];then
                action "$USER$num create success." /bin/true
        else
                action "$USER$num create failed." /bin/false
        fi
done

使用 openssl -rand -base64 8 生成的随机密码更好
