linux – 编写脚本以使用预定义的密码创建多个用户

useradd -m -s /bin/false users_in_the_users.txt

并从passwords.txt填写密码两次(以确认密码)

这是脚本

#!/bin/bash

# Assign file descriptors to users and passwords files
exec 3< users.txt
exec 4< passwords.txt
exec 5< passwords.txt

# Read user and password
while read iuser <&3 && read ipasswd <&4 ; do
  # Just print this for debugging
  printf "tCreating user: %s with password: %sn" $iuser $ipasswd
  # Create the user with adduser (you can add whichever option you like)
  useradd -m -s /bin/false $iuser
  # Assign the password to the user,passwd must read it from stdin
  passwd $iuser
done

问题是,它没有填写密码.还有一件事,我希望脚本能够填写两次密码.

有什么建议？
