Go 语言文件重命名指南

package main

import (

    "os"
)

func main() {
    err := os.Rename("old-file.txt", "new-file.txt")
    if err != nil {
        fmt.Println(err)

    err := os.Rename(oldPath, newPath)
    if err != nil {

}

package main

    dir := "data"
    oldName := "file1.txt"

    // 检查是否存在要重命名的文件
    if _, err := os.Stat(filepath.Join(dir, oldName)); err != nil {
        fmt.Println("File not found")
        return

    // 执行重命名操作
    err := os.Rename(filepath.Join(dir, oldName), filepath.Join(dir, newName))
    if err != nil {
        fmt.Println(err)
        return

    fmt.Println("File successfully renamed")
}
