How to identify log files differences between two log files?

[gyambqt]

For example I have two log files: A and B

A has

a

b

c

B has

c

b

c

So I want to compare the two files line by line and put the difference in another table such as

tablename=Compare_result

line_no      records_from_a   records_from_b   

1                          a                      c

SAS logs are unstructured text and will differ between executions starting with the execution date. Any small change in logging options will cause changes to the SAS log and especially on which line log messages appear. 

I suggest you take a more targeted approach for what you want to collect and let us know.

Looks for any utility that does comparison of text files. Notepad++, UltraEdit, DIFF, I'm a big fan of BeyondCompare.

Me too! I'm a long time BeyondCompare user and never seen a "better" utility for text comparison that's so rich in functionality yet so intuitive to use.

For what purpose do you want to compare log files?
