我需要能够在我的Linux (Fedora 10)上创建用户帐户，并通过bash脚本自动分配密码(如果需要，也可以采用其他方式)。
通过Bash创建用户很容易，例如:
[whoever@server ]# /usr/sbin/useradd newuser
是否可以在Bash中分配密码，功能类似于此，但自动:
[whoever@server ]# passwd newuser
Changing password for user testpass.
New UNIX password:
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[whoever@server ]#
当前回答
我在自己的shell脚本中进行了测试。
$new_username表示新创建的用户 $new_password表示新密码
是被久远
echo "$new_password" | passwd --stdin "$new_username"
对于 Debian/Ubuntu
echo "$new_username:$new_password" | chpasswd
对于 OpenSUSE
echo -e "$new_password\n$new_password" | passwd "$new_username"

请使用sudo权限运行以下脚本，通过脚本创建用户。
注意:此脚本支持所有linux操作系统，如Redhat, Centos, Ubuntu, suse, kali, Arch, Bitname, BSD....等
#!/bin/bash

#purpos: Linux user creation with a storng password
clear
#echo "Hi, I am a function to create sudo user with strong password. Kindly share following information"
echo -e "\n\n\n"
printf "\e[6;33mHi, I am a function to create sudo user with a strong password. Kindly share following information\e[0m";echo
read -p "user name:- " name #input name
read -p "complete path for $name home directory? example: /home/$name :- " home #user home path
( useradd -m -d $home $name -s /bin/bash ) > /dev/null 2>&1
pass=$(cat /dev/urandom |tr -dc "[[:graph:]]" |head -c16)
(echo -e "$pass\n$pass" | passwd $name ) > /dev/null 2>&1
echo " "
printf "\e[6;33m-----------------------------Copy below credentials-------------------------\e[0m";echo
echo -e "User:- $name\nHomeDir:- $home\npassword:- $pass"
#svalue=$(cat /etc/sudoers |grep -i root |grep -i all|tail -n1 |awk '{$1=""}1')
svalue=$(cat /etc/sudoers |grep -i root |grep -i all|tail -n1 |awk '{print $2}')
echo "${name} ${svalue} NOPASSWD:ALL" >> /etc/sudoers && echo “Remark:- User $name is a sudo user”
下面的代码可以在Ubuntu 14.04中运行。在其他版本/linux变体中使用它之前请尝试一下。
# quietly add a user without password
adduser --quiet --disabled-password --shell /bin/bash --home /home/newuser --gecos "User" newuser
# set password
echo "newuser:newpassword" | chpasswd
您可以在bash脚本中使用expect。
