source
source === 在当前Shell环境中从指定文件读取和执行命令。 ### 概要 source filename [arguments] ### 主要用途 - 执行文件并从文件中加载变量及函数到执行环境 #### 参数 filename：要执行的文件 arguments（可选）：传递给文件的参数 #### 返回值 source返回文件最后一个命令的返回值，如果文件不能读取则会失败 #### 错误用法 - 文件在`$PATH`中找不到。 - 文件未给出。 ### 例子 - 在一些工具的执行过程中，会把环境变量设置以"export XXX=XXXXXX"或"declare XXX=XXXXXX"的形式导出到 一个文件中，然后用source加载该文件内容到执行环境中。 - 读取和执行/root/.bash_profile文件。 ```shell [root@localhost ~]# source ~/.bash_profile ``` ### Q&A Q：`source`和`sh`在执行文件方面有什么区别？ A：`sh`的执行是在子shell中，`source`会使得被执行文件的变量及函数加载进当前终端环境内（除去函数内local修饰的变量等）；建议您参考`export`命令的 **知识点** 部分 ### 注意 1. 该命令是bash内建命令，相关的帮助信息请查看 `help` 命令。
