bash - passwd:当我运行我创建的 Bash 脚本时，Debian 上出现无法识别的选项 '--stdin' 错误

Question

我正在使用 Debian。我正在学习 Bash 脚本。我正在创建一个脚本来创建新用户并设置密码问题是我得到 passwd: unrecognized option '--stdin'错误

那是我的脚本:

#!/bin/bash
read -p "Please Enter Your Real Name: " REAL_NAME 
read -p "Please Enter Your User Name: " USER_NAME 
useradd -c "${COMMENT}" -m ${USER_NAME} 
read -p "Please Enter Your Password: " PASSWORD
echo ${PASSWORD} | passwd --stdin ${USER_NAME}
passwd -e ${USER_NAME}

Answer 1

没有--stdin选项，并且您需要用引号保护您的变量。

这是一个工作版本:

#!/bin/bash
read -p "Please Enter Your Real Name: " REAL_NAME 
read -p "Please Enter Your User Name: " USER_NAME 
useradd -c "${COMMENT}" -m ${USER_NAME} 
read -p "Please Enter Your Password: " PASSWORD
echo -e "$PASSWORD\n$PASSWORD" |passwd "$USER_NAME"
passwd -e ${USER_NAME}
