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!
