I've written a shell script to create user accounts. The script reads user account name and password from a text file and create account with those info. When I execute the script it successfully creates the accounts, but when I try to log in to those accounts I can't log in due to Invalid password, please try again error.

我编写了一个shell脚本来创建用户帐户。该脚本从文本文件中读取用户帐户名和密码，并使用这些信息创建帐户。当我执行脚本时，它成功创建了帐户，但是当我尝试登录这些帐户时由于密码无效而无法登录，请再次尝试错误。

Here is the script I used to create the user accounts:

这是我用来创建用户帐户的脚本：

file_name="t.txt"

while read user pass
do
    useradd -p ${pass} ${user}
done < $file_name

EDIT-1: t.txt file contains the user account information: space separated username and password per line. Here is the snippet of the file:

EDIT-1：t.txt文件包含用户帐户信息：空格分隔的每行用户名和密码。这是文件的片段：

user1 abcXYZ
user2 DEFxyz
user3 ijkLMN

EDIT-2: When I follow the method recommended by Steve Kline it shows me following result: (still the created accounts can't be logged in with the given password)

编辑2：当我按照史蒂夫克莱恩推荐的方法时，它显示以下结果:(仍然无法使用给定的密码登录创建的帐户）

passwd: unrecognized option '--stdin'
Usage: passwd [options] [LOGIN]

Options:
  -a, --all                     report password status on all accounts
  <---------------------------------- SKIPPED ------------------------------->
  -x, --maxdays MAX_DAYS        set maximum number of days before password
                                change to MAX_DAYS

Adding user user1  with the password  abcXYZ123

Still the created accounts can't be logged in with the given password

仍然无法使用给定密码登录创建的帐户

So your current method is adding plaintext passwords to /etc/shadow.

所以你当前的方法是在/ etc / shadow中添加明文密码。

Using your script as is... Created this. Mind you, I added a few digits at the end of your the password to match the standard 8 characters to suppress the "are you sure" prompts.

按原样使用你的脚本......创建了这个。请注意，我在密码末尾添加了几个数字以匹配标准的8个字符，以禁止“你确定”的提示。

user1:abcXYZ123:16963:0:99999:7:::
user2:DEFxyz142:16963:0:99999:7:::
user3:ijkLM1564:16963:0:99999:7:::

The users files

[root@localhost ~]# cat t.txt s.txt
user1 abcXYZ123
user2 DEFxyz142
user3 ijkLM1564
user4 abcXYZ123
user5 DEFxyz142
user6 ijkLM1564

The Script

#!/bin/bash -e
#Adding user1, user2, user3 using your method.
file_name="t.txt"
while read user pass
do
    #useradd ${user} -p ${pass}
    useradd -p ${pass} ${user}
    echo "Adding user "${user}"  with the password  "${pass}
done < $file_name

#Adding user4, user5, user6 using the recommended method.
file_name="s.txt"
while read user pass
do
    #useradd ${user} -p ${pass}
    useradd ${user}
    echo "${pass}" | passwd --stdin ${user}
    echo "Adding user "${user}"  with the password  "${pass}

done < $file_name

Using both syntaxes, produced these results in /etc/shadow

使用这两种语法，在/ etc / shadow中生成这些结果

user1:abcXYZ123:16963:0:99999:7:::
user2:DEFxyz142:16963:0:99999:7:::
user3:ijkLM1564:16963:0:99999:7:::
user4:$1$NpazYQAn$tlhfQLlP0CaFiUeNeK8HW.:16963:0:99999:7:::
user5:$1$4z8G4gvh$v0jzcV5xbhWixU1LG9mwW.:16963:0:99999:7:::
user6:$1$cBkcYJkJ$7A.j6E3gy/umUcVmY0tgt0:16963:0:99999:7:::

So, therefor the method I posted works. Update: Ubuntu working method below. This the stdin is confirmed for Rhel based systems.

因此，我发布的方法是有效的。更新：Ubuntu工作方法如下。这个stdin被确认用于基于Rhel的系统。

useradd ${user}
echo "${pass}" | passwd --stdin ${user}

If your heart is absolutely set on using that method, I would suggest installing mkpasswd and using this syntax.

如果您的心脏完全使用该方法，我建议安装mkpasswd并使用此语法。

 useradd -p $(mkpasswd ${pass}) ${user}

Update for Ubuntu Passwd stdin

更新Ubuntu Passwd stdin

echo ${user}:${pass} | /usr/sbin/chpasswd
