使用带参数的 bash 脚本创建用户

使用带参数的 bash 脚本创建用户

我正在尝试编写一个脚本来创建 (s)ftp 用户，但它一直失败，我不知道为什么。如果我回显该命令，就可以了，我可以复制并粘贴它来创建用户，但如果我在 bash 脚本中执行该命令，则无法创建用户。

我得到的唯一错误是 useradd 命令的帮助部分。

有人知道我做错了什么吗？

#!/bin/bash
# at the top are all the functions  at the bottem is the execution order
username() 
{
echo Enter the username.
read USERNAME
echo 
echo 
echo 

if [ -n "$USERNAME" ]; then
        :
        else
            echo "You didn't supply a username"
            username
         exit 1
fi
echo "the username you have selected is " $USERNAME
read -p "Is this the username you would like to use? Yy/Nn  " yn
case $yn in
    [Yy]* ) echo ;;
    [Nn]* ) username;;
    * ) echo "Please answer yes or no."; username;;
 esac
  }
groups()

groeps=($(cat /etc/group | grep ftponly))  #productie
