Windows Subsystem for Linux 显示 Linux 发行版吗？

有包裹屏幕抓取使用 ASCII 启动画面从 CLI 显示您的 Ubuntu 发行版：

WSL Bash 屏幕抓取

还有一个名为温斯凯尼在 Windows 环境中运行 Linux 时将显示 Windows 徽标，但不支持 WSL（适用于 Linux 的 Windows 子系统）。

有没有办法在 WSL 中显示反映 Windows 徽标的 ASCII CLI Linux 发行版启动画面？

答案1

温斯凯尼

我选了其中之一Github WinScreenybash 脚本并将其修改如下：

修改后的代码如下：

我不会花很多时间来剖析它，但你会注意到它是一些 Linux 内核和一些 Windows 内核的混合体。

例如，这个 Linux 内核行显示你的 CPU 信息：

cpu=$(awk -F':' '/model name/{ print $2 }' /proc/cpuinfo | head -n 1 | tr -s " " | sed 's/^ //')

另一方面，此 Windows 内核行显示您的主板型号：

board=`/mnt/c/Windows/System32/wbem/WMIC.exe baseboard get product | tail -2 | tr -d '\r '`

天气、日历和时间

有些人喜欢 Windows 10 (WSL) 上的 Ubuntu Bash 终端启动画面的顶部。如果您希望显示天气、日历和当前时间，可以在此处找到说明：我如何才能获得这个终端启动画面？
