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，问题是我遇到passwd: unrecognized option '--stdin'错误

那是我的剧本：

#!/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，您需要用引号保护变量。

这是一个有效的版本：

#!/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}

Answer 2

在 Debian 10 @ Docker 镜像上测试

echo -e "badpass\nbadpass" | passwd urname

这适用于 /bin/bash，而不适用于 /bin/sh

echo "urname:badpass" | chpasswd

这将适用于 /bin/sh 和 /bin/bash

passwd：运行创建的Bash脚本时，Debian上出现无法识别的选项'--stdin'错误
