rename a csv file in go

To rename a CSV file in Go, you can use the os package's Rename method. Here's an example:

main.go
package main

import (
    "os"
)

func main() {
    oldName := "file.csv"
    newName := "new_file.csv"

    err := os.Rename(oldName, newName)
    if err != nil {
        // handle error
    }
}

16 lines

In this example, we use the Rename method to rename the file file.csv to new_file.csv. If the renaming is successful, no error will be returned. If an error occurs, it will be returned and you should handle it according to your program's logic.
