我知道这听起来很奇怪，但这确实发生了。我以文件执行的方式设置了我的文件.profile（用回声检查它）。我没有收到任何错误，并且别名已在另一台机器上工作。.bashrc.bash_aliases
我使用以下命令来查看注册了哪些别名。
echo $(alias | cut -d '=' -f 1 | sort -u)
我把它放在.bash_aliases文件中，它显示了我的别名。然后我.bashrc在调用文件后立即将其放入文件中.bash_aliases。令人惊奇的是，刚刚创建的别名和印出来了，消失了！他们不再存在了！
为了更好地展示它，我将向您提供登录时的输出以及文件的内容。

答案1
您正在.bashrc子 shell 中运行。哪个退出。
坏的：
bash ~/.bashrc
您需要获取该文件的来源。
source ~/.bashrc
或者
. ~/.bashrc
