Golang : Create and resolve(read) symbolic links
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
