Master Go language file renaming technology

In the Go language, files can be easily renamed using the os.Rename function. This function accepts two parameters: the original file path and the new file path. Here are the steps: Define the original and new file paths. Use the os.Rename function to rename files. Check if error handling was successful.

Master Go language file renaming technology

In Go language, file renaming can be done through os.Rename Function is easy to implement. This function receives two parameters: the original file path and the new file path.

package main

import (
    "fmt"
    "os"
)

func main() {
    // 定义原始和新的文件路径
    originalPath := "original.txt"
    newPath := "renamed.txt"

    // 重命名文件
    err := os.Rename(originalPath, newPath)
    if err != nil {
        fmt.Println(err)
        return
    }

    // 重命名操作成功
    fmt.Println("File renamed successfully.")
}

Practical case:

Suppose there is a file named notes.txt and you want to rename it to important_notes .txt. You can use the following code:

package main

import (
    "fmt"
    "os"
)

func main() {
    // 定义原始和新的文件路径
    originalPath := "notes.txt"
    newPath := "important_notes.txt"

    // 重命名文件
    err := os.Rename(originalPath, newPath)
    if err != nil {
        fmt.Println(err)
        return
    }

    // 重命名操作成功
    fmt.Println("File renamed to important_notes.txt")
}
