RE: Out of topic :Compare 2 data files in unix

Another nice utility utility is sdiff.
It is a side by side Diff. It will concatenate the two files SIDe-BY-SIDE and have a middle column that will indicate whethere the lines are common or different or is an addition. Let me demonstrate

[111]/ora% cat A.txt
This is the 1st line
This is the 2nd line
This is the 3rd line
This is the 4th line
There is a slight difference here

[112]/ora% cat B.txt
This is the 1st line
This is the 3rd line
This is the 4th line
This is the 5th line
There is a slight differebce here

[113]/ora% sdiff A.txt B.txt

This is the 1st line                                               This is the 1st line
This is the 2nd line                                            <  
This is the 3rd line                                               This is the 3rd line
This is the 4th line                                               This is the 4th line
There is a slight difference here                               |  This is the 5th line
                                                                >  There is a slight differebce here

Options to sdiff
-w How wide you want the result window to be. If the file is 80 char wide you want it to be '-w 165'.
-s show only differences not identical lines

Warning. Make sure the files are ordered/sorted using UNIX 'sort'. Same warning goes for using 'comm'
