python版本：
代码如下:
#!/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：
代码如下:
package main
import (
"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 %sn", 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 %vn", 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("nn total number:%dn", count)
}
