thanks for clarification RudiC.

Actually there are only 6 log files which covers the whole day of logs( sometimes a combination of *gz and *Z files or all *gz files or all *Z files depending on the log size upon rotation).
Logs will be huge when (g)unzip, im afraid of having an FS issue by doing so i decided to use zcat | grep and gzgrep. Im sorry but im such a newbie and not so familiar with
"awk" command as you recommended.

Code:

Example logs on the archive:

/archive/2013-Jan-10$ 
        364M Jan 10 00:02 log.2013-Jan-10.00-00-50.Z
         75M Jan 10 04:00 log.2013-Jan-10.04-00-23.gz
         98M Jan 10 08:01 log.2013-Jan-10.08-00-32.gz
       174M Jan 10 12:02 log.2013-Jan-10.12-01-08.gz
        176M Jan 10 16:02 log.2013-Jan-10.16-01-23.gz
        354M Jan 10 20:02 log.2013-Jan-10.20-01-23.Z

/archive/2013-Jan-11$ 
        373M Jan 11 00:02 log.2013-Jan-11.00-00-53.Z
         83M Jan 11 04:01 log.2013-Jan-11.04-00-26.gz
        100M Jan 11 08:02 log.2013-Jan-11.08-00-31.gz
        344M Jan 11 12:02 log.2013-Jan-11.12-01-07.Z
        340M Jan 11 16:02 log.2013-Jan-11.16-01-23.Z
        362M Jan 11 20:02 log.2013-Jan-11.20-01-27.Z


/archive/2013-Jan-18$ 
        371M Jan 18 00:02 log.2013-Jan-18.00-00-52.Z
        91M Jan 18 04:01 log.2013-Jan-18.04-00-27.gz
        119M Jan 18 08:01 log.2013-Jan-18.08-00-31.gz
        154M Jan 18 12:02 log.2013-Jan-18.12-01-18.gz
         87M Jan 18 16:02 log.2013-Jan-18.16-01-40.gz
        105M Jan 18 20:02 log.2013-Jan-18.20-01-07.gz

The scripts will look like this:

Code:

date=`date +"%Y-%h-%d"`        
domainlist="4prd 5prd 6prd 7prd 8prd"
for domain in $domainlist
   do
     if [ -f /archive/$date/* ] ; then
                    # ^--- check if logs are present in the archive dir
        ls -l /archive/$date/* | grep Z
                    # ^--- check for *Z files
            if [ $? -eq 0 ] ; then
                zcat /archive/$date/*Z | grep "$domain" >> /archive/$date/$domain.txt
                    # ^--- grep "domain" for *Z files
                gzgrep "$domain" /archive/$date/*gz >> /archive/$date/$domain.txt
                    # ^--- grep "domain" for *gz files
                gzip -f /archive/$date/$domain.txt 
                  # ^--- archive has *Z files, perform the ff commands above, but the TIMESTAMP on the output file may sometimes won't be in order.
            else
                gzgrep "$domain" /archive/$date/*gz >> /archive/$date/$domain.txt
                gzip -f /archive/$date/$domain.txt
                # ^--- archive has no *Z files
            fi
        else
        echo ">>Logs not found, kindly check archive directory.."
     fi
  done

Kindly let me know if you have better solution for this. I would really appreciate your response. Thanks!

function::ctime

function::ctime

FUNCTION:(3stap)					      Time utility functions						  FUNCTION:(3stap)

NAME

       function::ctime - Convert seconds since epoch into human readable date/time string

SYNOPSIS

	   ctime:string(epochsecs:long)

ARGUMENTS

       epochsecs
	   Number of seconds since epoch (as returned by gettimeofday_s)

DESCRIPTION

       Takes an argument of seconds since the epoch as returned by gettimeofday_s. Returns a string of the form

       "Wed Jun 30 21:49:08 1993"

       The string will always be exactly 24 characters. If the time would be unreasonable far in the past (before what can be represented with a
       32 bit offset in seconds from the epoch) the returned string will be "a long, long time ago...". If the time would be unreasonable far in
       the future the returned string will be "far far in the future..."  (both these strings are also 24 characters wide).

       Note that the epoch (zero) corresponds to

       "Thu Jan 1 00:00:00 1970"

       The earliest full date given by ctime, corresponding to epochsecs -2147483648 is "Fri Dec 13 20:45:52 1901". The latest full date given by
       ctime, corresponding to epochsecs 2147483647 is "Tue Jan 19 03:14:07 2038".

       The abbreviations for the days of the week are 'Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', and 'Sat'. The abbreviations for the months are
       'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', and 'Dec'.

       Note that the real C library ctime function puts a newline ('
') character at the end of the string that this function does not. Also note
       that since the kernel has no concept of timezones, the returned time is always in GMT.
