python生成随机二进制文件 

 1 import random
 2 def genFile(filename,block=1,size=1):
 3         f=open(filename,"wb")
 4         content=""
 5         #for j in range(1024*1024):
 6         for j in range(1):
 7                 content=bytes(b"")
 8                 #for i in range(1024):
 9                 for i in range(1):
10                         c=chr(random.randint(0,255)).encode('utf-8')
11                         content=content+c
12                 f.write(content)
13  
14 print(len(sys.argv))
15 if len(sys.argv) != 2:
16         print("usage:\t"+sys.argv[0]+"\toutfilename")
17         sys.exit(1)
18 genFile(sys.argv[1],1024,1024*1024)
