Hi,
I have two files one (abc.txt) is having approx 28k records and another (bcd.txt) on is having 112k records, the length of each files are varried.
I am trying to look up abc.txt file with bcd.txt based on length, where ever abc.txt records are matching with bcd.txt I am successful match the records with bcd, but I am unable to fetch the records which are not matching with bcd.txt.
abc.txt
bcd.txt
I want the mismatch in each file are as below:
below is my script which I tried for matching of the records, but its is taking almost 5 hours, and next I am unable to find the mismatch records for both the files.
Please help me on this, this will save a lot of manual work at my end.
Regards,
Ram
