我在这里看到了 Windows 10 下的 Ubuntu Bash 终端启动画面：Windows Subsystem for Linux 显示 Linux 发行版吗？
我怎样才能改变我的~/.bashrc以在常规 Ubuntu 中获得类似的启动画面，如下所示？：
答案1
nowbash 脚本
笔记：2018 年 4 月 28 日更新Ubuntu 18.04 LTS
最重头的是显示这一点的启动组件：
$ now

是的，埃德蒙顿的气温确实是 -14 度，体感温度为 -23 度。这是度过长周末的好时机，可以在家里玩刚刚发布的《古墓丽影 2013》！也许可以温习一下简历，然后搬到温哥华或蒙特利尔去……

保存“~/.bashrc”文件的更改。
要显示您需要的 Ubuntu 信息screenfetch：
sudo apt install screenfetch
有类似的展示包可供screenfetch选择！
如果您想要相同的命令提示符，但命令之间有“─────────”分隔线，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。在本例中，分隔线的宽度为 92 个字符，并且gnome-terminal首选项也相应设置。
