我在Windows 10终端启动画面下看到一个Ubuntu Bash：Linux的Windows子系统显示Linux发行版？

如何更改我的文件~/.bashrc以在常规Ubuntu中获得类似的初始屏幕？

now bash脚本

注意：针对Ubuntu 18.04 LTS更新于2018年4月28日

繁重的工作是显示以下内容的启动组件：

是的，在埃德蒙顿，确实是-14，感觉像-23。这是度过悠闲周末的美好时光，让他们可以玩新到的古墓丽影2013！也许重新整理一下简历即可搬到温哥华或蒙特利尔...

保存“〜/ .bashrc”文件更改。

要显示Ubuntu信息，您需要screenfetch：

sudo apt install screenfetch

有类似的显示包，screenfetch所以货比三家！

如果要在命令提示符之间使用“──────────分隔行，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

注意分隔线的长度与screenfetch输出的宽度一致。在这种情况下，它的宽度为92个字符，并且相应gnome-terminal地设置了首选项。
