I have a log file that is not more than 10KB (File size can go up to 2 MB max) and I want to find if atleast one group of these strings occurs in the files. These strings will be on different lines like,

> 
> ACTION:.......
> 
> 
> INPUT:...........
> 
> 
> RESULT:..........
> 
> 
> 

I need to know atleast if one group of above exists in the file. And I have do this about 100 times for a test (each time log is different, so I have reload and read the log), so I am looking for fastest and bets way to do this.

I looked up in the forums for finding the fastest way, but I dont think my file is too big for those silutions.

Thansk for looking.
