Copy a folder in go

Is there an easy way to copy a directory in go?
I have the following function:

err = CopyDir("sourceFolder","destinationFolder")


Nothing so far has worked, including libraries such as github.com/cf-guardian/guardian/kernel/fileutils

One important thing to note is that I need to preserve directory structure, including the sourceFolder itself, not simply copy all contents of the folder.

CopyDir

cp

os/exec

An easy and lazy way would be to use the copy command of your system. This example just works on systems with the command cp (so not for Windows)

func CopyDir(src, dst string) error
cmd := exec.Command("cp", "a")
log.Printf("Running cp -a")
return cmd.Run()



To preserve of the directories is not so easy to implement, so to use the system program for that is ok. But that solution does not work on all systems, because it needs an external program. I would just use it for internal purposes.

This package seems to do exactly what you want to do, give it a try.

From the readme:

err := Copy("your/source/directory", "your/destination/directory")
