How to export "cvs diff" to file from eclipse?

I think i might be silly, but I am tired completely searching solution for this...

So, the question is:
1. I have one module, say module1. Where i have lots files inside the modules
2. Using eclipse i can able to find the difference between 2 tags for each file...
3. so far fine, I want to find out the way so that i can see difference for the same module for 2 tags (all files included) and want to export that info to some other file...

Hope I am clear in explanations on my question.. Can any one help me to achieve this?

BTW, I am using Eclipse 3.4 ( I don't think it matters, but including if in case.. )

say, if:
1. i checkout module for tag1 (but tag2 is already there)
2. I wan to send the diff file from tag1 to tag2

How can I achieve this here...?
Gibu GeorgeChief Technology OfficerCommented:
This is my understanding

You have two tags in the CVS tag1 and tag2

You want to take the diff between a particular file in tag1 and tag2

is this correct?

I am sorry, I think because of my bad English you could not able to understand i think..

1. module1 checked out by tag1
2. I want the difference in file for this module1 (already checked out using tag1) after comparing with tag2

Note: module1-which internally has around 100 files...

Gibu GeorgeChief Technology OfficerCommented:
I don't there is any way to take the diff between two tags. You need to check out both the tags and take the diffs using  windiff or winmerge or similar tools

This seems quite different, than "cvs diff" command output:

1. I have one module, say module1
2. There are around 100 files, one file is say This source has around 2000 lines of code.
3. I simply changed one line in by adding one extra comment...!!!
4. I want to send the difference now for entire module1, to my boss
5. So, I right clicked->Team->create patch
6. I see the file changed and created patch. so far so good... :)
7. I open that create patch file, and I see over 4000 lines, but i just added one extra comment. It tried giving entire source lines even though i didn't change it....

I see there are couple of options creating before patch, but all are same in the way it creates...
Is there any way, I can see only the changed lines in created patch.

That might be white spce issues, or new line char between your cvs repository os and your os

Seems right.... my CVS running under Redhat 7.1 (VM) and my desk machine is running under XP.

How I can handle this, any idea?
Gibu GeorgeChief Technology OfficerCommented:
The character set on both should be made same, I think that is the only way

I am not 100% sure
