1、screenFetch 是一个能够在截屏中显示系统/主题信息的命令行工具。它可以在 Linux，OS X，FreeBSD 以及其它的许多类Unix系统上使用。来自 man 手册的说明：
可以用来生成那些漂亮的终端主题信息和用 ASCII 构成的发行版标志，就像如今你在别人的截屏里看到的那样。它会自动检测你的发行版并显示 ASCII 版的发行版标志，并且在右边显示一些有价值的信息。
安装 screenfetch
克隆screenFectch库: git clone https://github.com/KittyKatt/screenFetch.git Cloning into ‘screenFetch‘... remote: Counting objects: 3659, done. remote: Total 3659 (delta 0), reused 0 (delta 0), pack-reused 3659 Receiving objects: 100% (3659/3659), 3.60 MiB | 993.00 KiB/s, done. Resolving deltas: 100% (2111/2111), done.
移动到指定文件夹下： #mv screenFetch /usr/bin/ 添加可执行权限： #chmod +x /usr/bin/screenFetch/ 执行命令： #/usr/bin/screenFetch/screenfetch-dev

2、linux_logo 程序生成一个彩色的 ANSI 版企鹅图片，还包含一些来自 /proc 的系统信息
只需按照你的 Linux 发行版安装相应的软件包即可：
Debian/Ubutnu/Mint #apt-get install linux_logo CentOS/RHEL/旧版 Fedora #yum install linux_logo Fedora Linux v22+ 或更新版本 # dnf install linux_logo
运行：
$ linux_logo

kvm-host可以用这个命令查看内置的标志列表： $ linux_logo -f -L list

Remember to also use -a to get ascii version.
$ linux_logo -L 14

或者只是随机看看一些 Linux 标志： $ linux_logo -f -L random_xy
SSSSS OOOO L AA RRRRR III SSSSS S O O L A A R R I S S O O L A A R R I S SSSS O O L AAAAAA RRRRR I SSSS S O O L A A R R I S S O O L A A R R I S SSSSS OOOO LLLLLL A A R R III SSSSS Linux Version 3.10.0-514.el7.x86_64, Compiled #1 SMP Tue Nov 22 16:42:41 UTC 2016 Two 4.2GHz Intel i9 Processors, 8GB RAM, 16800 Bogomips Total kvm-host
输入下列命令：
$ screefetch -h
$ linux_logo -h
4、可以在登录界面输出你的 Linux 发行版徽标。要输出默认徽标，你可以在 ~/.bashrc文件的最后添加以下内容
if [ -f /usr/bin/linux_logo ]; then linux_logo; fi
如果没有~/.bashrc 文件，你需要在当前用户的 home 目录下新建一个
在添加以上内容后，你只需要注销并重新登录即可看到你的发行版的默认徽标
其实你也可以在登录后输出任意随机图标，只需加入以下内容：
if [ -f /usr/bin/linux_logo ]; then linux_logo -L random_xy; fi Last login: Thu Aug 24 00:05:10 2017 from 192.168.0.190 #### ### ### ## ## ## ## ## ## #### #### ## ### ### ### #### ### ### #### ### ## ## ## ## ## ## ## ## ## ### ## ## ## ## ## ##### ## #### ## #### ## ##### ## ###### ## ## ## ## ## ## ## ## ### ### ## ## ## ## | #### #### ###### #### ### ### ## ## ###### ## ##### `------------------------------------------------------------- l i n u x
也可以直接指定徽标所在的位置来显示你自己的徽标。
$ linux_logo -D /path/to/ASCII/logo
如果你想使用 ASCII 徽标而不是含有颜色的 ANSI 徽标，则使用如下命令
$ linux_logo -a > /etc/issue.net
5、用命令在终端循环打印logo：
for i in {1..30};do linux_logo -f -L $i;sleep 2;done
