本文實例講述了Go語言清除文件中空行的方法。分享給大家供大家參考。具體實現方法如下：
這里使用Go語言讀取源文件，去掉空行，并寫到目標文件
復制代碼代碼如下:

package main
import (
"os"
"bufio"
"fmt"
)
func DeleteBlankFile(srcFilePah string, destFilePath string) error {
srcFile, err := os.OpenFile(srcFilePah, os.O_RDONLY, 0666)
defer srcFile.Close()
if err != nil {
return err
}
srcReader := bufio.NewReader(srcFile)
destFile, err := os.OpenFile(destFilePath, os.O_WRONLY|os.O_CREATE, 0666)
defer destFile.Close()
if err != nil {
return err
}
var destContent string
for {
str, _ := srcReader.ReadString('/n')
if err != nil {
if err == io.EOF {
fmt.Print("The file end is touched.")
break
} else {
return err
}
}
if 0 == len(str) || str == "/r/n" {
continue
}
fmt.Print(str)
destFile.WriteString(str)
}
return nil
}
func main() {
DeleteBlankFile("e://src.txt", "e://dest.txt")
}
