Your answer may be identical to the JOJ answer in the first several lines.

However, the main problem you meet now is Runtime Error. And the exit code of your program is 1, which should be 0.

Please double check your code to solve this problem and try again.

mumsh $ 123
123
1.txt
2.txt
driver
mumsh
mumsh_memory_check
