Python读取Linux进程内存并转储到文件

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()

到目前为止，一切正常(转储进程的内存)，但我无法将数据保存到文件中。我做错了什么？

文件是否会被写入到您不希望的某个位置(看起来它们将被写入当前目录)？
