1. import sys
   
2. import pickle
   
3. import re
   
4. 
   
5. # save last pos
   
6. last_file = 'check.pkl'
   
7. if len(sys.argv) < 3:
   
8.     print("Usage: python check.py log key1 key2 ... keyn")
   
9.     sys.exit(1)
   
10. 
    
11. log_file = open(sys.argv[1])

14.     key.append(i)
    
15.
