批量创建10个系统帐号name01-name10并设置密码（密码为随机8位字符串
脚本
#!/bin/bash
. /etc/init.d/functions
[ $UID -ne 0 ] && {
echo "only allow root to exec this cmd."
exit 1
}
for n in `seq -w 10`
do
pass="$(echo $RANDOM|md5sum|cut -c 2-9)"
useradd name$n &>/dev/null &&\
echo $pass|passwd --stdin name$n &>/dev/null
if [ $? -eq 0 ];then
action "useradd name$n" /bin/true
else
action "useradd name$n" /bin/false
fi
echo -e "name$n\t$pass" >> user.txt
done
要点：
数字前加0的方法：seq -w 00 10;
echo {01..10}
