请问你的是linux吗？如果是linux可以借助/proc来获取。

import os

class File(object):

def __init__(self, file_path):

if not os.path.exists(file_path):

raise OSError(‘{file_path} not exist’.format(file_path = file_path))

self.file_path = os.path.abspath(file_path)

def status(self):

open_fd_list = self.__get_all_fd()

open_count = len(open_fd_list)

is_opened = False

if open_count > 0:

is_opened = True

return {‘is_opened’: is_opened, ‘open_count’: open_count}

def __get_all_pid(self):

“””获取当前所有进程”””

return [ _i for _i in os.listdir(‘/proc’) if _i.isdigit()]

def __get_all_fd(self):

“””获取所有已经打开该文件的fd路径”””

all_fd = []

for pid in self.__get_all_pid():

_fd_dir = ‘/proc/{pid}/fd’.format(pid = pid)

if os.access(_fd_dir, os.R_OK) == False:

continue

for fd in os.listdir(_fd_dir):

fd_path = os.path.join(_fd_dir, fd)

if os.path.exists(fd_path) and os.readlink(fd_path) == self.file_path:

all_fd.append(fd_path)

return all_fd

if __name__ == “__main__”:

_file = File(‘/tmp/a.txt’)

print(_file.status())
