var delCmd = &cobra.Command{
	Use:   "del [task id]",
	Short: "Deletes a task given an identifier",
	Long: `Del (asynqmon del) will delete a task given an identifier.

The command takes one argument which specifies the task to delete.
The task should be in either scheduled, retry or dead queue.
Identifier for a task should be obtained by running "asynqmon ls" command.

Example: asynqmon enq d:1575732274:bnogo8gt6toe23vhef0g`,
	Args: cobra.ExactArgs(1),
	Run:  del,
}

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

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

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