Make a path relative from absolute

https://gist.github.com/arxdsilva/4f73d6b89c9eac93d4ac887521121120

dir, err := os.Getwd()

    if err != nil {

        log.Fatal(err)

    }

You may use path.Join() or filepath.Join().
For example:

base := "/home/bob"
fmt.Println(path.Join(base, "work/go", "src/github.com"))

Output:

/home/bob/work/go/src/github.com
