批量创建10个系统帐号oldboy01-oldboy10并设置密码，密码为随机数，要求字符和数字等混

#!/bin/sh

function getpassword {

##产生随机密码 if [ -n "$1" ] then length=$1 else length=8

fi

chars='abcdefghijkmnpqrstuvwxyzABCDEFGHJKMNPQRSTUVWXYZ23456789'

charlength=echo $chars |wc -m |sed 's#^[ \t]##g'

pw=''

for nn in seq ${length} do

r=$[$RANDOM%$charlength+1]

w=echo $chars |cut -c $r-$[$r] pw=$pw$w done echo $pw }

[ -f name_password.txt ] && rm -fr name_password.txt

for name in seq 10 do #判断数字是否为10 if [ ${name} -lt 10 ] then name="0"$name fi #生成用户 useradd oldboy$name PASSWORD=$(getpassword 10) echo $PASSWORD|passwd --stdin oldboy$name &2>/dev/null echo -e "用户名：" oldboy$name "密码：" $PASSWORD " \n " >> name_password.txt done cat name_password.txt\
