终端启动画面有天气，日历，时间和Sysinfo？
我在Windows 10终端启动画面下看到了一个Ubuntu Bash： 用于Linux的Windows子系统显示Linux发行版？
如何更改我的~/.bashrc以在常规Ubuntu中获得类似的启动屏幕，如下所示：
now bash脚本
注意： 2018年4月28日更新为Ubuntu 18.04 LTS
重物是飞溅组件，显示了这一点：

是的，在埃德蒙顿真的是-14，感觉就像-23。 这是一个度过漫长周末的好时机，可以玩新近到来的古墓丽影2013！ 也许刷上那个简历来搬到温哥华或蒙特利尔……
这是代码：

保存`〜/ .bashrc“文件更改。
要显示Ubuntu信息，您需要使用screenfetch ：
sudo apt install screenfetch
有类似的显示包到screenfetch所以购物！
如果希望命令提示符与“─────────”命令之间的分界线相同，请更改以下行：
if [ "$color_prompt" = yes ]; then PS1='─────────────────────────────────────────────────────────────────────────────────────────── ${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' else PS1='─────────────────────────────────────────────────────────────────────────────────────────── ${debian_chroot:+($debian_chroot)}\u@\h:\w\$ ' fi unset color_prompt force_color_prompt
请注意，分隔线的长度与screenfetch输出的宽度一致。 在这种情况下，它是92个字符宽，并相应地设置gnome-terminal首选项。
