Really appreciate your time in writing the awk script.
But each of these files have 500K records.
But I have managed to write a perl script for the diff file. i.e.
The above code works perfectly for generating the diff file i.e. depending upon the primary keys (here taken 2) the outfile contains the records that exists in file1 but not in file2 and the records that exists in file2 but not in file1.
I need to compare the whole record(line) if the primary keys in file1 matches with the primary keys in file2. If both the lines are equal then discard else write to the outfile.
Could someone please help me out in order to the above step.
Thanks a lot for providing the awk script.
As you said the awk looks simpler and shorter.
I have ran the two awk scripts that you have provided to me for the two different files and have generated the two same.txt and same1.txt files.
File1.diff --> Records that exists in File1 but not in File2
same.txt --> Records that exists in both the files
File2.diff --> Records that exists in File2 but not in File1
same1.txt --> Records that exists in both the files'
The file size of the same.txt and same1.txt is different.
--> 506108009 Jun 15 01:50 same.txt
--> 505878904 Jun 15 01:52 same1.txt
So, is there anyway that we can capture the records if the Primary Keys ($38 and $82) of both the files matches but the data in the other columns is not the same.
To solve the above issue, I thought once we have the files same.txt and same1.txt we should compare the number of characters in the a line in File1 with number of characters in a line in file2 , if there is a change then write to a file else discard (do nothing or leave it)
Could you please share any ideas to solve the above issue. It would be really grateful.
I need to take 2 input files and create 1 output based on matches from each file. I am looking to match field #1 in both files (Userid) and create an output file that will be a combination of fields from
both file1 and file2 if there are any differences in the fields 2,3,4,5,or 6.
