golang批量修改文件名

package main

import 
    "fmt"
    "io/ioutil"
    "strings"

    "os"
    "path/filepath"
)

func main) {
    path := "."
    files, _ := ioutil.ReadDirpath)
    for index, f := range files {
        // 带扩展名的文件名
        fullFilename := f.Name)
        fmt.Printlnindex)
        fmt.PrintlnfullFilename)
        //扩展名
        fileExt := filepath.Extf.Name))
        fmt.PrintlnfileExt)
        // 不带扩展名的文件名
        filenameOnly := strings.TrimSuffixfullFilename, fileExt)
        fmt.PrintlnfilenameOnly)
        //将每个文件名后面加上1，扩展名不变
        //os.Renamepath+"\"+f.Name), path+"\"+fmt.Sprintf"%s%s%s", filenameOnly, "1", fileExt))
        //将每个文件名中的1替换为2，扩展名不变
        os.Renamepath+"\"+f.Name), path+"\"+fmt.Sprintf"%s%s", strings.ReplacefilenameOnly, "1", "2", 1), fileExt))
    }
}
