Zenity:如何创建用户并更改其密码?

Question

我是zenity的新手，想创建一个GUI来创建新用户和密码。我的代码是这样的：

#!/bin/bash
zenity --info --text='Welcome to Account Creation Wizard'
zenity --entry --text='What do you want to set your username as?' > username
zenity --password > test
cat username >> username1
cat username >> username1
cat test >> test1
cat test >> test1
useradd -m < username1
passwd < username1 < test1
rm test test1
rm username username1
exit

但它不起作用。在终端中，我得到这个：

[root@archevaris Desktop]# ./UserCreator.sh
Usage: useradd [options] LOGIN
useradd -D
useradd -D [options]
Options:
--badnames                do not check for bad names
-b, --base-dir BASE_DIR       base directory for the home directory of the
new account
--btrfs-subvolume-home    use BTRFS subvolume for home directory
-c, --comment COMMENT         GECOS field of the new account
-d, --home-dir HOME_DIR       home directory of the new account
-D, --defaults                print or change default useradd configuration
-e, --expiredate EXPIRE_DATE  expiration date of the new account
-f, --inactive INACTIVE       password inactivity period of the new account
-g, --gid GROUP               name or ID of the primary group of the new
account
-G, --groups GROUPS           list of supplementary groups of the new
account
-h, --help                    display this help message and exit
-k, --skel SKEL_DIR           use this alternative skeleton directory
-K, --key KEY=VALUE           override /etc/login.defs defaults
-l, --no-log-init             do not add the user to the lastlog and
faillog databases
-m, --create-home             create the user's home directory
-M, --no-create-home          do not create the user's home directory
-N, --no-user-group           do not create a group with the same name as
the user
-o, --non-unique              allow to create users with duplicate
(non-unique) UID
-p, --password PASSWORD       encrypted password of the new account
-r, --system                  create a system account
-R, --root CHROOT_DIR         directory to chroot into
-P, --prefix PREFIX_DIR       prefix directory where are located the /etc/* files
-s, --shell SHELL             login shell of the new account
-u, --uid UID                 user ID of the new account
-U, --user-group              create a group with the same name as the user
New password: Retype new password: passwd: password updated successfully
[root@archevaris Desktop]#

它实际上所做的是更改我的root密码:P(这个 bash 脚本执行起来有点危险，但谢天谢地，我在 VM 快照中做到了(

那么，如何解决这个问题呢？我应该对代码进行哪些更改？

要通过zenity获取用户名和密码，这将起作用：

export INFO=$(zenity --password --username)

$INFO将被管道分割，因此如果您的用户名是"Fred"，密码是"123abc"，$INFO将如下所示：

Fred|123abc

从这里开始，只需使用cut来分隔数据：

USERNAME=$(echo $INFO | cut -d"|" -f1)
PASSWORD=$(echo $INFO | cut -d"|" -f2)
