Question

我想创建一个bash脚本，用户可以通过输入两次来选择用户名，密码和确认密码。如果密码不匹配，则应提示用户再次输入密码。如果密码匹配，脚本应该创建一个passwordhash，否则再次询问，直到它正确。

到目前为止，我有以下代码，但我不确定这是否是正确的方法。以下bash脚本是否有问题？

# read username
read -p "Username: " username

# read password twice
read -s -p "Password: " password
echo 
read -s -p "Password (again): " password2

# check if passwords match and if not ask again
while [ "$password" != "$password2" ];
do
    echo 
    echo "Please try again"
    read -s -p "Password: " password
    echo
    read -s -p "Password (again): " password2
done

# create passwordhash
passwordhash=`openssl passwd -1 $password`

# do something with the user and passwordhash

减少冗长的方法：

#!/bin/bash

read -p "Username: " username
while true; do
    read -s -p "Password: " password
    echo
    read -s -p "Password (again): " password2
    echo
    [ "$password" = "$password2" ] && break
    echo "Please try again"
done
