批量建立10個系統帳號name01-name10並設定密碼（密碼為隨機8位字串

指令碼

#!/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

要點：

數字前加0的方法：seq  -w 00 10;

echo  {01..10}
