Here is the the program
package main
import (
"fmt"
"log"
"os/user"
)
func main() {
username, err := user.Current()
if err != nil {
log.Fatal(err)
}
if username != "root" || username != "someuser" {
fmt.Println("You are currently logged in as:" + username)
fmt.Println("You need to be root or someuser")
}
}
Here is the output
go run user.go
# command-line-arguments
./user.go:14:14: invalid operation: username != "root" (mismatched types
*user.User and string)
./user.go:14:36: invalid operation: username != "someuser" (mismatched
types *user.User and string)
./user.go:15:53: invalid operation: "You are currently logged in as:" +
username (mismatched types string and *user.User)
I am not sure how to handle mismatched types string and *user.User.
