I want to find the md5sum of files starting with "10" ( could be exe, doc, pdf etc) hence not checking the file extension but only the start two digits. So far I've a script to traverse through the directory and print out all such files but couldn't get the checksum to be printed for each of them:
def print_files(file_directory, file_extensions=['10']): ''' Print files in file_directory with extensions in file_extensions, recursively. ''' # Get the absolute path of the file_directory parameter file_directory = os.path.abspath(file_directory) # Get a list of files in file_directory file_directory_files = os.listdir(file_directory) # Traverse through all files for filename in file_directory_files: filepath = os.path.join(file_directory, filename) # Check if it's a normal file or directory if os.path.isfile(filepath): # Check if the file has an extension of typical video files for file_extension in file_extensions: # Not a reqd file, ignore #if not filepath.endswith(file_extension): if not filename.startswith(file_extension) or len(filename) != 19: continue # We have got a '10' file! print_files.counter += 1 ## TRYING TO READ AND PRINT MD5 USING HASHLIB/ DOESNT WORK### hasher = hashlib.md5() with open(filename, 'rb') as afile: buf = afile.read(65536) while len(buf) > 0: hasher.update(buf) buf = afile.read(65536) # Print it's name print('{0}'.format(filepath)) print hasher('{0}.format(filepath)').hexdigest() print '\n' elif os.path.isdir(filepath): # We got a directory, enter into it for further processing print_files(filepath) if __name__ == '__main__': # Directory argument supplied if len(sys.argv) == 2: if os.path.isdir(sys.argv[1]): file_directory = sys.argv[1] else: print('ERROR: "{0}" is not a directory.'.format(sys.argv[1])) exit(1) else: # Set file directory to CWD file_directory = os.getcwd() print('\n -- Looking for Required Files in "{0}" -- \n'.format(file_directory)) # Set the number of processed files equal to zero print_files.counter = 0 # Start Processing print_files(file_directory) # We are done. Exit now. '
