Get the parent path

Another option is the path package:

package main
import "path"

func main() {
   s := "/Users/s05333/go/src/appcmd"
   t := path.Dir(s)
   println(t == "/Users/s05333/go/src")
}

https://golang.org/pkg/path#Dir

Take a look at the filepath package, particularly filepath.Dir:

wd,err := os.Getwd()
if err != nil {
    panic(err)
}
parent := filepath.Dir(wd)

Per the docs:

Dir returns all but the last element of path, typically the path's directory.
