Yoda,
>>Just curious, why don't you simply create a new file rather than replacing?
- I like this idea and took this approach creating a new file, and has less work just using a loop with variable to build the file1 from the data of file2.

The awk solutions are also good, and yet to go through. Thank you all for help and suggestion.

Also, Yoda & RudiC both awk solutions worked and good.
>> RudiC
what if the No. of lines in file2 don't equate the No. of c7.s and/or m7.s in file1?

- well in 2nd file has the equal number of data for the matching c7 and m7 entries, as my effort for making one HTML file from the cpu & memory usage data from another file of 5 different server, in a 2 row 5 column table. There is another set of entry of server names that is above.

So the table would come with an email in HTML format from the server itself and easy to look in the email body.

s (in short the server names).

s75 s76 s77 s78 s71
CPU(%) values...
MEM(%) values...



Thanks ..

diff3(1)						      General Commands Manual							  diff3(1)

Name
       diff3 - 3-way differential file comparison

Syntax
       diff3 [-ex3] file1 file2 file3

Description
       The command compares three versions of a file, and publishes the ranges of text that disagree, flagged with the following codes:

	  ====	      all three files differ

	  ====1       file1 is different

	  ====2       file2 is different

	  ====3       file3 is different

       The type of change needed to convert a given range of a given file to some other is indicated in one of these ways:

	  f : n1 a    Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.

	  f : n1 , n2 c
		      Text is to be changed in the range line n1 to line n2.  If n1 = n2, the range may be abbreviated to n1.

       The original contents of the range follows immediately after a c indication.  When the contents of two files are identical, the contents of
       the lower-numbered file is suppressed.

Options
       -3   Produces an editor script containing the changes between file1 and file2 that are to be incorporated into file3.

       -e	   Produces an editor script containing the changes between file2 and file3 that are to be incorporated into file1.

       -x	   Produces an editor script containing the changes among all three files.

Examples
       Under the -e option, publishes a script for the editor that incorporates into file1 all changes between file2 and  file3  -  that  is,  the
       changes	that would normally be flagged ==== and ====3.	Option -x (-3) produces a script to incorporate only changes flagged ==== (====3).
       The following command applies the resulting script to `file1':
       (cat script; echo '1,$p') | ed - file1

Restrictions
       Text lines that consist of a single `.'	defeat -e.

Files
       /tmp/d3?????
       /usr/lib/diff3
