Difference between two huge files
Hi,
As per my requirement, I need to take difference between two big files(around 6.5 GB) and get the difference to a output file without any line numbers or '<' or '>' in front of each new line.
As DIFF command wont work for big files, i tried to use BDIFF instead.
I am getting incorrect number of records.
I have done the following test:
I have got a dat file with a few million records in it and to generate a another file i have used sed '1,100d' oldfile > newfile
so i am using Bdiff oldfile newfile | sed -n '/^</p' > DIFF.DAT
The output(DIFF) should be having 100 records in it. But i am getting an output with several records in it.
Could anyone help me out from this situation?
Thanks
Sue
