如何一次运行存在于不同目录中的多个go程序?

I have different directories such as DBconnection , APIRequest , APIResponse etc.

All codes are interconnected. How can I run these at a time. The go run .go needed to be exist all files in a directory.

But I have multiple directories.

Any kind of help or suggestion will be appreciated

If I understand your question correctly: you could write a little shell script executing them one after the other:

#!/usr/bin/env bash

go run /ParentPath/DBconnection/execfile.go
go run /ParentPath/APIRequest/execfile.go
go run /ParentPath/APIResponse/execfile.go

You could also create a go program executing the different packages in go routines, then you do not need to start multiple go programs.
