source /etc/init.d/functions
for((i=01;i<=10;i++));do
user=addUser$i
password=`uuidgen`
  echo "$user" >>/tmp/pass.txt
  echo "$password" >>/tmp/pass.txt
  echo "--------------------$user--------------------"
useradd $user
  if [ $? != 0 ];then
    action "user $user" /bin/false
    exit 1
    else
    action "user $user" /bin/true
fi   
echo "$password"|passwd --stdin $user
  if [ $? != 0 ];then
    action "user $password" /bin/false
    exit 1
    else
    action "user $password" /bin/true
fi   
  echo "--------------------$user--------------------"
done

2.創建一個腳本，批量刪除上一個腳本所創建的用戶

user=addUser$i
userdel -r $user
  if [ $? != 0 ];then
    action "userdel $user" /bin/false
    exit 1
    else
    action "userdel $user" /bin/true
