前端之家收集整理的这篇文章主要介绍了
golang遍历某个目录下的文件，并读取文件名到一个csv文件，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
package main
import (
"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 string
if len(os.Args) > 1 {
path = os.Args[1]
} else {
path,_ = os.Getwd()
}
PrintFilesName(path)
fmt.Println("done!")
}
