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"

其他回答

单行程序创建一个带有主目录和密码的sudo用户。

useradd -m -p $(openssl passwd -1 ${PASSWORD}) -s /bin/bash -G sudo ${USERNAME}

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

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。

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”

来自IBM (https://www.ibm.com/support/knowledgecenter/ssw_aix_61/com.ibm.aix.cmds1/chpasswd.htm):)

创建一个文本文件,输入text.txt,并按如下方式填充用户:密码对:

user1:password1
user2:password2
...
usern:passwordn

保存“text.txt”文件并运行

cat text.txt | chpassword

就是这样。该解决方案是(a)可伸缩的,(b)不需要在命令行上打印密码。
