#encoding=utf-8

import os
import sys

def main(path,depth=0):
    print depth * '|' + '|_',os.path.basename(path)
    if os.path.isdir(path):
        for item in os.listdir(path):
            newpath = path + '/' + item
            newdepth = depth + 1
            main(newpath,newdepth)

if __name__ == '__main__':
    main(sys.argv[1])
