的Python阅读Linux进程的内存和转储到文件

Question

我有以下脚本：

import sys, os 

pid = sys.argv[1] 
maps_file = open("/proc/%s/maps" % pid, 'r') 
mem_file = open("/proc/%s/mem" % pid, 'r') 
for line in maps_file.readlines(): # for each mapped region 
    m = re.match(r'([0-9A-Fa-f]+)-([0-9A-Fa-f]+) ([-r])', line) 
    if m.group(3) == 'r': # if this is a readable region 
     start = int(m.group(1), 16) 
     end = int(m.group(2), 16) 
     mem_file.seek(start) # seek to region start 
     chunk = mem_file.read(end - start) # read region contents 
     #print chunk, # dump contents to standard output 
     mem_dump = open(pid+".bin", "wb") 
     mem_dump.write(str(chunk,)) 
     mem_dump.close() 
maps_file.close() 
mem_file.close() 

所有workds以及（倾销进程的内存），但迄今为止我无法保存数据到文件。我究竟做错了什么？

难道是文件正在写入你不期望的地方（看起来他们将被写入当前目录）？
