How to Rename and Move a File in Golang?
In the Go language, you are allowed to rename and move the existing file to a new path with the help of the Rename() method. This method is used to rename and move a file from the old path to the new path.
- If the given new path already exists and it is not in a directory, then this method will replace it. But OS-specific restrictions may apply when the given old path and the new path are in different directories.
- If the given path is incorrect, then it will throw an error of type *LinkError.
- It is defined under the os package so, you have to import os package in your program for accessing Remove() function.
Syntax:
func Rename(old_path, new_path string) error
Example 1:
// Go program to illustrate how to rename // and move a file in default directory package main import ( "log" "os" ) func main() { // Rename and Remove a file // Using Rename() function Original_Path := "w3wiki.txt" New_Path := "gfg.txt" e := os.Rename(Original_Path, New_Path) if e != nil { log .Fatal(e) } } |

Example 2:
