Golang : Exit, terminating or aborting a program


Tags : golang exit abort error

There are times where a controlled termination of a program is required rather than proceeding ahead. This is a quick example on how to exit/terminating/aborting a program in Golang.

 package main

 import (
 "fmt"
 "os"
 )

 func main() {
 // will not be executed because of defer causing to Exit happen before this line 
 defer fmt.Println("Doing something...") 

 fmt.Println("Oh no, fatal error!")
 os.Exit(1)
 }

Sample output :

go run exit.go

Oh no, fatal error!

exit status 1

If the program is compiled, there WILL BE NO exit status number.

go build exit.go

./exit

Oh no, fatal error!
