python版本：
代码如下:
#!/usr/bin/env pythonimport 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 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)}
