Windows下 oh-my-posh 的配置，具体操作见官方文档
1. 安装 oh-my-posh
Ubuntu
curl -s https://ohmyposh.dev/install.sh | bash -s
如果 Ubuntu 上还没有安装 curl 的话，先安装 curl：
sudo apt install curl
另外，Ubuntu 系统下用 curl 安装 oh-my-posh，默认安装位置在 /home/USER/.local/oh-my-posh
Archlinux
paru -S oh-my-posh
Archlinux 系统下用 pacman 安装 oh-my-posh 的话，默认安装位置应该是在 /usr/share/oh-my-posh
2. 配置 bashrc
在安装完成后，打开安装位置处 oh-my-posh 文件夹下的 themes 文件夹，其中包含了官方的示例主题（可以在此基础上自由配置）。
我们从中找到 catppuccin_mocha.omp.json 文件，即 catppuccin_mocha 主题的配置文件，复制文件路径，然后打开终端，输入
vim ~/.bashrc
进入 bashrc 开始为终端配置 oh-my-posh，在其中添加下面这行代码：
# 此处的 location 为 oh-my-posh 的安装位置
eval "$(oh-my-posh init bash --config /location/catppuccin_mocha.omp.json)"
添加完成后，保存退出，重启终端，就可以看到 oh-my-posh 主题美化后的终端界面了
3. 自定义主题
在第 2 步中，我们使用的是官方提供的样例主题，实际上 oh-my-posh 的主题文件是可以自由配置的。
配置文件中，主要修改的控件有 blocks、segments，具体用法过多，请移步官方文档。
比如下面这个主题配置，是小生自己编辑出来的，以供参考
