// enqCmd represents the enq command
var enqCmd = &cobra.Command{
	Use:   "enq [task id]",
	Short: "Enqueues a task given an identifier",
	Long: `Enq (asynqmon enq) will enqueue a task given an identifier.

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

The task enqueued by this command will be processed as soon as the task 
gets dequeued by a processor.

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

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

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