golang遍历某个目录下的文件，并读取文件名到一个csv文件

package mainimport ("encoding/csv""fmt""os""path/filepath""container/list")var outputFileName string = "filesName.csv"func CheckErr(err error) {if nil != err {panic(err)}}func GetFullPath(path string) string {absolutePath, _ := filepath.Abs(path)return absolutePath}func PrintFilesName(path string) {fullPath := GetFullPath(path)listStr := list.New()filepath.Walk(fullPath, func(path string, fi os.FileInfo, err error) error {if nil == fi {return err}if fi.IsDir() {return nil}name := fi.Name()if outputFileName != name{listStr.PushBack(name)}return nil})OutputFilesName(listStr)}func ConvertToSlice(listStr *list.List)[]string{sli := []string{}for el:= listStr.Front(); nil != el; el= el.Next(){sli = append(sli, el.Value.(string))}return sli}func OutputFilesName(listStr *list.List) {files := ConvertToSlice(listStr)//sort.StringSlice(files).Sort()// sort  f, err := os.Create(outputFileName)//f, err := os.OpenFile(outputFileName, os.O_APPEND | os.O_CREATE, os.ModeAppend)CheckErr(err)defer f.Close()f.WriteString("\xEF\xBB\xBF")writer := csv.NewWriter(f)length := len(files)for i:= 0; i < length; i++{writer.Write([]string{files[i]})}writer.Flush()}func main() {var path stringif len(os.Args) > 1 {path = os.Args[1]} else {path, _ = os.Getwd()}PrintFilesName(path)fmt.Println("done!")}
