I have initiated 50 processes and in one file say start_time, I have stored when process was started and in another file say end_time, I have stored when process finished.files are like below -Start time - Start time for Process A : 15/09/26 21:02:13Start time for Process B : 15/09/26 20:06:14Start time for Process C : 15/09/26 13:20:52Start time for Process D : 15/09/26 11:23:46End time file End time for Process B : 15/09/26 21:13:38End time for Process D : 15/09/26 12:31:29End time for Process A : 15/09/26 22:06:11End time for Process C : 15/09/26 12:17:10Now I want to calculate execution time for each processlike Process A : 10 minsProcess B : 5 minsetc.
subtract dates from two files for same process
regular expression
