在终端中初始输入后，Bash 源文件可以正常工作

我正在弄乱我的 bash 设置，我决定将其移至版本控制，我做了一些更改，并将.bashrc和.bash_profile移至我的 dotfiles 存储库。这似乎导致了一个相当不寻常的错误，似乎我的源文件正在运行，但视觉变化仅在输入某些内容后才适用，例如

这是在打开终端后

如果我输入任何内容，它就会按预期工作

我经常通过 SSH 进入我的机器，所以这是我采用的设置，我很确定它远非最佳实践，但在我今天所做的更改之前，它运行得相对良好。不幸的是，我没有对 bashrc 和配置文件进行版本控制，所以我不知道到底是什么导致了这个问题。我目前的知识并不能让我知道罪魁祸首是什么，这太奇怪了。

我在 Ubuntu 22.04，Wayland 上，确切的点文件可以是找到这里。 我在用starship.rs作为我的提示。昨天一切都运行良好，在我进行更改之前，（更改很少，我认为我没有添加任何内容，只是删除了一些评论，我肯定删除了一些我认为不重要的东西）

如果我在不移除输出的情况下获取来源，例如

if [ -e ~/.bash_aliases ]; then
    source ~/.bash_aliases #>/dev/null 2>&1
fi

我得到以下输出

Welcome to nikola-B450M-DS3H!

它来自初始化我的提示和所有内容的文件，这意味着它的来源正确，但由于某种原因，它没有在终端的初始打开时应用。奇怪的是，如果我在末尾添加reset或以期解决问题，它仍然会存在，但如果我手动输入 clear 或 reset，它就会起作用。所以我完全迷茫了clear.bash_profile
