Golang : Execute function at intervals or after some delay

Problem :

You want to execute functions at intervals - such as polling a remote terminal every 30 seconds or count the number of processes running in the memory after 10 seconds.

Solution :

Use the time.Tick() function. For example :

 package main

 import (
  "fmt"
  "time"
 )

 func pollRemoteTerm(n time.Duration) {
  timestamp := time.Now().Local()

  for _ = range time.Tick(n * time.Second) {

 str := "Polling remote terminal data at <some remote terminal name> at "+ timestamp.String()
 fmt.Println(str)
  }
 }

 func main() {

  go pollRemoteTerm(10) // very useful for interval polling

  select {} // this will cause the program to run forever
 }
