Do we have a wiser diff?

[arking1981]

Hi dears,

Do we have a wiser diff?

I want to compare two csv files and analyze the change to get what is added, deleted and modified. For example:

File1:

2,2,0,0030D303FE82,s002c02p0,10.87.134.222,acceSS7
2,2,1,0030D303FE50,s002c02p1,10.87.134.223,acceSS7
2,2,2,0030D300372E,s002c02p2,10.87.134.224,acceSS7
2,2,3,0030D300372D,s002c02p3,10.87.134.225,acceSS7
2,2,4,0030D300372A,s002c02p4,10.87.134.226,acceSS7
2,2,5,0030D300372B,s002c02p5,10.87.134.227,acceSS7

File2:

2,2,1,0030D303FE50,s002c02p1,10.87.134.223,acceSS7
2,2,2,0030D300372E,s002c02p2,10.87.134.224,acceSS7
2,2,3,0030D300372D,s002c02p3,10.87.134.225,acceSS7
2,4,0,0800FFFFFFFF,s002c04p0,0.0.0.0,acceSS7
2,5,0,0800FFFFFFFF,s002c05p0,0.0.0.0,acceSS7

diff file1 file2

2d1
< 2,2,0,0030D303FE82,s002c02p0,10.87.134.222,acceSS7
6,7c5,6
< 2,2,4,0030D300372A,s002c02p4,10.87.134.226,acceSS7
< 2,2,5,0030D300372B,s002c02p5,10.87.134.227,acceSS7

> 2,4,0,0800FFFFFFFF,s002c04p0,0.0.0.0,acceSS7
> 2,5,0,0800FFFFFFFF,s002c05p0,0.0.0.0,acceSS7

The first change is simple and diff is right. The second change is actually a deletion combined with an addition but diff can only tell it as a modification.

Any chance we have such a tool diff to tell what I want or another tool can do? Please advise.

Apologize for asking a stupid question and thanks a lot for your time.

Regards

Kang

What do you consider the a change vs. a delete then add?  diff(1) doesn't know the difference.

I supose you could take the output from diff and modify it to your needs.

indeed it is true.

If not for command line tool, you may consider tkdiff or beyond compare (may need to recompile on HP-UX).
