Why doesn't it work to manually do .sh under the bash shell? 为什么在 bash shell 下手动执行 .sh 无效？

[DOSforever]

我在 d:\cmder\config\profile.d 目录下修改了下 alias.sh 文件。然后在 bash 下输入 /d/cmder/config/profile.d/alias.sh 执行了这个文件，没有报任何错误，但为什么新增的 alias 没有？也就是执行后无效，应该如何做才能生效？

I modified the following alias.sh file in the d:\cmder\config\profile.d directory. Then enter /d/cmder/config/profile.d/alias.sh in bash and execute this file without any errors, but why is the new alias not? That is, it is invalid after execution, what should be done to take effect?
