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 ]#

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

这里有一个脚本，将为您.....
如果你愿意，你可以添加一个用户列表(或者只是一个用户)，一次完成，每个用户都有不同的密码。作为奖励，脚本的末尾会显示每个用户的密码. ....如果您愿意，您可以添加一些用户维护选项
如:
chage -m 18 $user
chage -M 28 $user
到将设置密码年龄等的脚本。
= = = = = = =
#!/bin/bash
# Checks if you have the right privileges
if [ "$USER" = "root" ]
then
# CHANGE THIS PARAMETERS FOR A PARTICULAR USE
PERS_HOME="/home/"
PERS_SH="/bin/bash"
# Checks if there is an argument
[ $# -eq 0 ] && { echo >&2 ERROR: You may enter as an argument a text file containing users, one per line. ; exit 1; }
# checks if there a regular file
[ -f "$1" ] || { echo >&2 ERROR: The input file does not exists. ; exit 1; }
TMPIN=$(mktemp)
# Remove blank lines and delete duplicates
sed '/^$/d' "$1"| sort -g | uniq > "$TMPIN"
NOW=$(date +"%Y-%m-%d-%X")
LOGFILE="AMU-log-$NOW.log"
for user in $(more "$TMPIN"); do
# Checks if the user already exists.
cut -d: -f1 /etc/passwd | grep "$user" > /dev/null
OUT=$?
if [ $OUT -eq 0 ];then
echo >&2 "ERROR: User account: \"$user\" already exists."
echo >&2 "ERROR: User account: \"$user\" already exists." >> "$LOGFILE"
else
# Create a new user
/usr/sbin/useradd -d "$PERS_HOME""$user" -s "$PERS_SH" -m "$user"
# passwdgen must be installed
pass=$(passwdgen -paq --length 8)
echo $pass | passwd --stdin $user
# save user and password in a file
echo -e $user"\t"$pass >> "$LOGFILE"
echo "The user \"$user\" has been created and has the password: $pass"
fi
done
rm -f "$TMPIN"
exit 0
else
echo >&2 "ERROR: You must be a root user to execute this script."
exit 1
fi

希望这能有所帮助。

在Debian和Red Hat上都可以工作的解决方案。依赖于perl，使用sha-512散列:
cat userpassadd
#!/usr/bin/env bash
salt=$(cat /dev/urandom | tr -dc A-Za-z0-9/_- | head -c16)
useradd -p $(perl -e "print crypt('$2', '\$6\$' . '$salt' . '\$')") $1
用法:
userpassadd jim jimslongpassword
它可以有效地作为一行程序使用，但你必须自己在正确的地方指定密码、盐和用户名:
useradd -p $(perl -e "print crypt('pass', '\$6\$$salt\$')") username
对于RedHat / CentOS，下面是创建用户、添加密码并使用户成为sudoer的代码:
#!/bin/sh
echo -n "Enter username: "
read uname
echo -n "Enter password: "
read -s passwd
adduser "$uname"
echo $uname:$passwd | sudo chpasswd
gpasswd wheel -a $uname
下面是我在Ubuntu 14.04上测试的。它是一个不需要任何用户输入的一行程序。
sudo useradd -p $(openssl passwd -1 $PASS) $USERNAME
摘自@Tralemonkey
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
#author: bablish jaiswal
#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”
