我想创建一个bash脚本，用户可以在其中选择用户名，密码并通过输入两次来确认密码。如果密码不匹配，则将提示用户再次输入密码。如果密码匹配，则脚本应创建一个密码哈希，否则请再次询问，直到正确为止。
到目前为止，我有下面的代码，但是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
