使用go和python递归删除.ds store文件的方法

python版本：

#!/usr/bin/env python
import os, sys;def walk(path):

print "cd directory:"+path

for item in os.listdir(path):


try:



if(item == ".DS_Store"):




global count




count = count+1




print " find file .Ds_Store"




os.remove(path+"/"+item)



else:




if(os.path.isdir(path+"/"+item)):





print " "+path+"/"+item+" is directory"





walk(path+"/"+item)




else:





print " "+path+"/"+item+" is file"


except OSError,e:



print e
 
if __name__=='__main__':

count = 0

if(len(sys.argv)>1):


root_dir = sys.argv[1]

else:


root_dir = os.getcwd()

walk(root_dir)

print "\ntotal number:"+str(count)

go语言版本：

package mainimport (

"flag"

"fmt"

"os"

"path/filepath"
)
func getFilelist(path string) int {

count := 0

err := filepath.Walk(path, func(path string, f os.FileInfo, err error) error {


if f == nil {



return err


}


if f.IsDir() {



fmt.Printf("cd directry %s\n", path)



return nil


}


if f.Name() == ".DS_Store" {



count++



println(" " + f.Name() + " is deleted")



os.Remove(path)


}


return nil

})

if err != nil {


fmt.Printf("filepath.Walk() returned %v\n", err)

}

return count
}
func main() {

flag.Parse()

root := flag.Arg(0)

count := 0

if root == "" {


crurrent_dir, _ := filepath.Abs(".")


count = getFilelist(crurrent_dir)

} else {


count = getFilelist(root)

}

fmt.Printf("\n\n total number:%d\n", count)
}
