// grepCmd represents the grep command
var grepCmd = &cobra.Command{
	Use:   "grep",
	Short: "The grep utility searches any given input files, selecting lines that match one or more patterns.",

	Long: `The grep utility searches any given input files, selecting lines that match one or more patterns.  By default, a pattern matches an input line if
     the regular expression (RE) in the pattern matches the input line without its trailing newline. Each input
     line that matches at least one of the patterns is written to the standard output. For example:

s3tools grep my-bucket "search string"`,
	Run: func(cmd *cobra.Command, args []string) {
		if len(args) < 2 {
			fmt.Println("You must provide bucket and a search pattern")
			return
		}

		bucket := args[0]
		pattern := args[1]

		path, err := cmd.Flags().GetString("path")
		if err != nil {
			fmt.Println("It was impossible to parse path parameter")
		}
		utils.GrepFiles(bucket, pattern, path)
	},
}

func init() {
	grepCmd.Flags().StringP("path", "p", "", "path where grep will look for")
	rootCmd.AddCommand(grepCmd)

	// Here you will define your flags and configuration settings.

	// Cobra supports Persistent Flags which will work for this command
	// and all subcommands, e.g.:
	// grepCmd.PersistentFlags().String("foo", "", "A help for foo")

	// Cobra supports local flags which will only run when this command
	// is called directly, e.g.:
	// grepCmd.Flags().BoolP("toggle", "t", false, "Help message for toggle")
