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 ..

comm

comm(1) 							   User Commands							   comm(1)

NAME

       comm - select or reject lines common to two files

SYNOPSIS

       comm [-123] file1 file2

DESCRIPTION

       The comm utility reads file1 and file2, which must be ordered in the current collating sequence, and produces three text columns as output:
       lines only in file1; lines only in file2; and lines in both files.

       If the input files were ordered according to the collating sequence of the current locale, the lines  written  will  be	in  the  collating
       sequence of the original lines. If not, the results are unspecified.

OPTIONS

       The following options are supported:

       -1	Suppresses the output column of lines unique to file1.

       -2	Suppresses the output column of lines unique to file2.

       -3	Suppresses the output column of lines duplicated in file1 and file2.

OPERANDS

       The following operands are supported:

       file1	A path name of the first file to be compared. If file1 is -, the standard input is used.

       file2	A path name of the second file to be compared. If file2 is -, the standard input is used.

USAGE

       See largefile(5) for the description of the behavior of comm when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

EXAMPLES

       Example 1: Printing a list of utilities specified by files

       If file1, file2, and file3 each contain a sorted list of utilities, the command

       example% comm -23 file1 file2  | comm -23 - file3

       prints a list of utilities in file1 not specified by either of the other files. The entry:

       example% comm -12 file1 file2 | comm -12 - file3

       prints a list of utilities specified by all three files. And the entry:

       example% comm -12  file2 file3 | comm -23 -file1

       prints a list of utilities specified by both file2 and file3, but not specified in file1.

ENVIRONMENT VARIABLES

       See  environ(5)	for  descriptions  of  the  following  environment  variables that affect the execution of comm: LANG, LC_ALL, LC_COLLATE,
       LC_CTYPE, LC_MESSAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0	All input files were successfully output as specified.

       >0	An error occurred.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
