The lines on file as
1 Jan 10:00 the chassis normal status
1 Jan 10:30 log I'd lost
1 Jan 12:30 interface down
1 Jan 1:00 power off system
2 Jan 11:00 the high temperature
2 Jan 2:00 the user log in successfully
And alot of statements like that so some statements useful and some statements no.
So the output like that
Down appear 10 times
Power off appear 1 time
Interface down 3 times
And I need the algorithm to suggest the most words and how many appear in file. And also how to reduce with certain pattern.
