package main
import (
"fmt"
"github.com/spf13/cobra"
)
func main() {
var strTmp string
rootCmd := &cobra.Command{
Use: "root",
Run: func(cmd *cobra.Command, args []string) {
fmt.Println(strTmp)
},
}
subCmd := &cobra.Command{
Use: "sub",
Run: func(cmd *cobra.Command, args []string) {
fmt.Println(strTmp)
},
}
rootCmd.PersistentFlags().StringVarP((&strTmp), "test", "t", "", "test required")
rootCmd.MarkPersistentFlagRequired("test")
