Here, We will learn how to set the value of the environment variable in go. We can do it by using Setenv() function in os package in go golang.
Function prototype:
func Setenv(key, value string) error
Paramters:
key: Environment variable name
value: To be set into variable
Return value:
Setenv() function in os package returns
an error, if any.
Example with code:
package main
import (
"fmt"
"os"
"log"
)
func main() {
err := os.Setenv("NAME", "Jon")
if err != nil {
log.Fatal(err)
}
err = os.Setenv("ADDR", "USA")
if err != nil {
log.Fatal(err)
}
name := os.Getenv("NAME")
addr := os.Getenv("ADDR")
fmt.Printf("Name: %s, Addr: %s\n", name, addr)
}
Output:
Name: Jon, Addr: USA
