背景

每个人linux开发工程师，都应该有属于自己的bashrc文件，这样会提高开发效率。

什么是bashrc

linux一般有系统级的bashrc(/etc/bash.bashrc)和profile(/etc/profile)以及个人用户的$HOME/.bashrc和$HOME/.profile
这里不再重复描述bashrc和profile的区别，自行去stackoverflow查看。

个人bashrc的一个实践

一般来说，个人需要添加有export, alias, function三种内容，一般有区分的分布在bashrc和profile中。（具体可以参考stackoverflow）
这里给出另一种更实用的实践：
将自己的内容单独出来一个文件：
.bash_yanyongwen
然后在$HOME/.bashrc中引用这个文件。
这样最大的好处就是：你的文件可以纳入代码管理（我放在公司的gitlab中管理），在不同的服务器上可以极快地部署。
同时，linux升级也不会影响你的文件（因为解耦）。

操作

只需要在$HOME/.bashrc中加入

if [ -f "$HOME/.bash_yanyongwen" ]; then
    . "$HOME/.bash_yanyongwen"
fi

将.bash_yanyongwen放入$HOME目录即可
