Golang os.Lstat() function is “used to get information about a file, without following symbolic links”. It accepts the name as an argument and returns the fileinfo struct.
Syntax
func Lstat(name string) (FileInfo, error)Parameters
name: It is the file or directory name for which you want to get the information.
Return value
The Lstat() function returns a FileInfo struct, which contains information about the file or directory, such as its size, mode, and modification time. If there is an error, the function returns an error value.
Example 1: Simple usage of os.Lstat() function
package main
import (
"fmt"
"os"
)
func main() {
fileInfo, err := os.Lstat("app.txt")
if err != nil {
fmt.Println(err)
return
}
fmt.Println(fileInfo)
}
Output
&{app.txt 0 420 {528096986 63811822410 0x102350580}
{16777232 33188 1 36339649 501 20 0 [0 0 0 0] {1676225610 528096986}
{1676225610 528096986} {1676225610 528096986} {1676225610 528096986}
0 0 4096 0 0 0 [0 0]}}Example 2: Checking for Symbolic Links
This example checks if a given file or directory is a symbolic link.
package main
import (
"fmt"
"log"
"os"
)
func main() {
fileName := "new.txt"
info, err := os.Lstat(fileName)
if err != nil {
log.Fatalf("Error retrieving file info: %s", err)
}
if (info.Mode() & os.ModeSymlink) != 0 {
fmt.Println(fileName, "is a symbolic link.")
} else {
fmt.Println(fileName, "is not a symbolic link.")
}
}Output
new.txt is not a symbolic link.That’s it!
