Script uses another perl script who outputs date as YYYYMMDDHHMMSS (ex. 20110425151745)
Well, then I put ls -la to calculate the size of yesterday's file, and today's file.
Problem is I don't know how to compare the size of yesterday's file ($fechayer) to today's file ($fechahoy) and then, if the difference of the size is 20% less than yesterday, abort script with error.
What would be the algorithm for calculating that difference of size in percentage?
if fechahoy<fechayer by more than 20% --->then abort
Hope you help me, thanks a lot!
