## 一、
### 1. 使用指令建立使用者

### 2. 快速建立多個使用者
- **2-1. 建立 Python 程式 create_users.py，並用此程式來建立 users.txt**
**create_users.py**

import os

min = 1    ## 
max = 40   ## 
userid = '10'
groupid = userid
usercmt = 'AIoT Users'
homedir = '/home/aiot'
shell = '/bin/bash'
userline = ''

while min < max+1:
    uname = 'aiot' + '{idx:02}'.format(idx=min)
    pwd = uname
    uid = userid + '{idx:02}'.format(idx=min)
    gid = uid
    hdir = homedir + '{idx:02}'.format(idx=min)
    userline = uname + ':' + pwd + ':' + uid + ':' + gid \
               + ':' + usercmt  + ':' + hdir  + ':' + shell
    print(userline)
    min += 1

**產生的 users.txt 內容範例**

aiot01:aiot01:1001:1001:AIoT Users:/home/aiot01:/bin/bash
aiot02:aiot02:1002:1002:AIoT Users:/home/aiot01:/bin/bash
...

- **2-2. 程式用法**
**注意：使用 newusers 指令時，users.txt 的檔名，似乎有限制。例如若執行 newusers users01-30.txt，就會無法建立成功！！**

## 方法一
python3 create_users.py > users.txt
chmod 600 users.txt
sudo newusers users.txt

## 方法二
sudo bash -c "python3 create_users.py | newusers"
