Compare 2 files the send output to a file
Hallo Friends,

I would like to compare two files, then write the difference between the two into output file then find a pattern then search for that pattern.

Code:
-bash-3.2$ cat BS_Orig_20141112.csv|head -20

Pax,

What have you tried?
Have you looked into sort, diff, and/or comm?

There is also grep to consider. What output are you expecting from the sample input.

I'm a little confused to the eventual output. Can you explain a little more about the eventual target. There may be other more efficient ways to deliver your requirement.



Is this actually the same as this post?
