Hi,

My file is Tab delimited. And first 2 lines Header are Trailer are of 14 fields and where as Transaction records (are around 56 fields). Sed command has to remove all lines other that which has value 5000 in 1st column and 0 in the 5th column.

Instead of a command. Can i make this into a batch file and perform all the changes on a click on the batch with out changing the file name?

Thanks,
Phani Akella
