Golang : Create and resolve(read) symbolic links



Tags : golang os-symlink symbolic os-readlink

Creating new symbolic link for a file and resolving(read) symbolic link back to the origin file is pretty straight forward in Golang with the os.Symlink and os.Readlink functions.

Here is an example on how to create and resolve symbolic link.

 package main

 import (
 "fmt"
 "os"
 )

 func main() {

 // create a new symbolic or "soft" link
 err := os.Symlink("file.txt", "file-symlink.txt")
 if err != nil {
 fmt.Println(err)
 os.Exit(1)
 }

 // resolve symlinks

 fileInfo, err := os.Lstat("file-symlink.txt")

 if err != nil {
 fmt.Println(err)
 os.Exit(1)
 }

 if fileInfo.Mode()&os.ModeSymlink != 0 {
 originFile, err := os.Readlink(fileInfo.Name())

 if err != nil {
 fmt.Println(err)
 os.Exit(1)
 }

 fmt.Println("Resolved symlink to : ", originFile)
 }

 }

Sample output :

Resolved symlink to : file.txt
