We have data files that are ftp'd every morning to a SUN server. The file names are exactly the same except for that each has the date included in its name. I have to write script to do 2 things:
STEP 1) Verify that the file arrived in morning.
STEP 2) Compare the file size of the current days file to the previous days file. If the current days file size is 30% smaller or less then the previous days, I will need to write a flag/indicator to a log file. (NOTE: The sizes should be very close in size every day, so any decrease to 30% or less would indicate it is missing data.)
